If you don't care about any of the explanation (I know I can be longwinded), just follow the bolded numbers in curly brackets at the beginning of some paragraphs. Follow each of these steps in order, and you can probably have this implemented in a few minutes. Note that this guide assumes some amount of Unix competency (being able to create directories, create files, sudo elevating to root access, etc). Also note that root access is only required where indicated, so you do not need to use sudo unless told to. We will be using xkb to add a "locking" (like Caps lock) numpad emulation to Linux. I would like my keys "jkluio789" to represent the numpad representations of the numbers "123456789", as well as a few other inclusions ("m,"->"0", "-"->numpad"-*", "."->numpad"."). I will toggle this "numpad mode" by using the key combination of ShiftMod4key where Mod4 is the modifier code for my operating system key (also called "Command" or "Windows Key", and sometimes assigned to the modifier code of Super or Hyper), and key is any of the keys used in my emulated numpad (such as "j" or ""). Simple modifications to this setup should be relatively simple after reading the full solution.To do this, we will define a custom xkb "type" file, which tells xkb how to interpret the various modifier keys we will use to initialize our keypad emulation, as well as a custom xkb "symbols" file, which tells xkb how each key we press should behave normally (Group 1), how it should behave during the numpad emulation (Group 2), and how to switch back and for between the two (Level 3 action for both groups). Finally, we will make our solution permanent by integrating it into the current xkbmap using sed each time we start a new session (so that our solution does not get erased each time xkb is updated).1 The first thing we will do is define a directory for us to keep our various files in. Yours can look like pretty much anything, but mine looks like thisOnce we have our directory tree, lets define the actual files in our solution. The first thing we will do is define our "type" file. This file will tell xkb how to move between "levels" (like how Shift capitalizes a letter, moving from the first level of a lowercase letter to an uppercase level of the uppercase letter). These levels are a bit difficult to grasp, particularly for native English speakers, but international keyboards use them to great effect for alternative letters and symbols, as well as diacritical marks. We will be using it to define how we intend to indicate a change in our keys.In other words, we tell it that we expect "level 1" behavior when no modifier is pressed (usually, a standard lower case letter when in our "normal mode"), "level 2" behavior when we hold the Shift key (usually, a standard upper case letter in our "normal mode"), and "level 3" behavior uwhen we hold both ShiftMod4 (a special case for our purposes, which we use to indicate that, when used to modify a key, the key will now switch between modes).2 Open a new file, which we will call togglekeypad. Copy the following codeblock into it, and save it into your types directory under home.xkbtypes. NOTE: You may need to change all instances of Mod4 to whatever modifier your "Command"/"Windows Key" button corresponds to (you might need to experiment, see this webpage under Modifier Keys for guidance) or whatever other modifier you would like.3 We must also copy this file to the directory /usr/share/X11/xkb/types/. This will require root privileges, which unfortunately kind of defeats the purpose of xkb being a user-space application, but I can't seem to get setxkbmap to recognize the file without doing this. Suggestions welcome!The next thing we will do it tell xkb what each key should do when modified in each of the ways we described in the types file. We will say that we want to use two Groups in our symbols file.This means that each key has two different general behaviors that we will switch between in some way, those behaviors being the normal typing behavior, and the new numpad emulation behavior. For each key, we will say that 1) we want to use the TOGGLEKEYPAD type, 2) we will define the symbols (i.e. what the computer sees) associated with each of the physical keys in both Groups for all Levels, and 3) we will define any actions (any special things that xkb should do) associated with each key for both Groups across all Levels. This sounds rather confusing, but should make a bit more sense when look at an example. The first key that we see in the symbols file I pasted below is the key. This corresponds to the "J" key on most keyboards, according to the map seen here (Figure 2). For this physical key, we are saying that, in normal mode: in level 1 (no modifiers, according to our type file) it will just type "j", and in level 2 (Shift modifier) it will just type "J". In level 3, it does something special: there is no symbol associated with level 3, but there is an action, and that action is to LockGroup(group2). In other words, change us over to our second group, our "Keypad" group.If we look on the next few lines, we see that we have more symbols and actions defined for group 2 for this same key. It says that, in level 1 (no modifiers) type no symbol, but RedirectKey(keycode). In other words, register this key as if we actually just pressed the key, which corresponds to the "1" on a keypad. (Note: we could have again put NoAction() and used the symbol KP_1, which is the symbol that key corresponds to, but I thought this would give the best compatibility). For level 2, do the same thing, but add the Shift modifier to the key. Finally, for level 3, we lock ourselves back to Group 1, "Standard" mode.4 Open a new file, which we will call togglekeypad_symbols. Copy the following codeblock into it, and save it into your types directory under home.xkbsymbols.5 To test the keypad configuration as it is, open a Terminal window and typeThis will grab the current settings of our xkb map (using setxkbmap - print) while setting the types used to completetogglekeypad (everything in the file /usr/share/X11/xkb/types/complete and also including our types file at /usr/share/X11/xkb/types/togglekeypad). It will then feed this into sed, which will add our symbols togglekeypad from our file togglekeypad_symbols into the used symbols files. Finally, we used xkbcomp to compile the new keymap.Note that, on my machine, NumLock is presumed to be off (because there is no numpad on my machine), so the numpad keys will actually send their primary functions to the computer, i.e. Home, End, PG Up, PG Down, etc. To get numbers typed when using the emulated numpad, hold Shift. I have tried various methods to get this behavior flipped (swapping the modifers argument between levels in the symbols file, assigning a new key to emulate the NumLock key and toggling it), but nothing has yet worked for me. Thankfully, though, when tested in Blender, it performs exactly as expected without need for Shift being held down.6 If things have gone horribly wrong at this point, then don't worry, just logout/login (or at worst restart), debug, and try again. If everything is working, let's make it permanent. There are certainly some more elegant ways to make our solution persistent between sessions, but the easiest and most reliable method for me was to simply put the above commands at the end of my /.bashrc file.I used the solution roosed here which adds a it of error checking, and added a it more (so I could see any error oututs).7 Oen the file .ashrc. Add the following scrit to the end of it:8 Uon restarting, the numad emulation should now e made ermanent!While the exlanation is long, the method itself it relatively short. The shortfalls are that Blender requires a locking method to roerly work, whereas I would have referred a holding method instead, and also that it requires root access to get xk to recognize our custom tyes file for some reason. However, overall, this aears to e working well for me. If you have any questions or suggestions, lease feel free to leave them elow! Related Questions.

So this means you have a classification rolem.You can reduce the dimensionality y aroximating and efficiently encoding the trajectory (references on request), and taking the first-difference of the mouse click frequency (i.e., if the frequency of clicks is not changing, store zero).

This is dictation software, ut it has a "feature" I hadn't learned aout yet, which is while the rogram is loaded, it intercets certain keys' inut, including the numeric keyad and * keys. I was ale to clear that out y going to that software's Tools-Otions-"Hot keys" menu and editing out those keys.This is very similar to the rolem and solution in this question, ut with a different iece of software doing the intercetion. So as a general answer to this tye of rolem, I would suggest that if some keys sto resonding sometimes, one might try shutting down various running rograms (esecially recently-installed ones) and then testing the keys, to see if any of them is causing it, and then looking for otions in that software to hoefully see what keys it intercets and adjust them to taste (or at least know what they are)------Caribou On Screen Keyboard Shift Key Not WorkingHere is a solution that will only work on Xorg, not Wayland.We will modify the binary file, /usr/lib/gnome-shell/libgnome-shell.so.Make a backup of the original file.View the portion of the file that we will modify.The output will look like this, showing that Caribou uses Gnome Shell's new LocalAdapter to handle virtual key presses.Comment out the part of the code that tells Caribou to use Gnome Shell's LocalAdapter. Caribou will then default to its own XAdapter, which works only in X11. Verify that /usr/lib/gnome-shell/libgnome-shell.so was modified correctly.The output will look like this, showing that the line has now been commented out.Disable Wayland and use X11 on the GDM (login) screen.Make sure WaylandEnable has been uncommented and that it is set to false in the GDM configuration.The output should look exactly like this.Finally, reboot to make the changes effective.Since the solution above is only a workaround, register on Launchpad and Bugzilla, and mark yourself as impacted, so this bug gets fixed...Undo / Revert ChangesIf your outputs from steps 4 and 5 match what is shown above, then the changes were made successfully.

It can be detrimental to switch keyboards. Switching keyboards can slow production down a lot - I have seen it many times. I get mad when someone changes my mouse acceleration speed... Editing for 12 hours a day gets you comfortable with computer lag and keyboard sensitivity. It's important!!!I find that for me, the grooves of the older Mac keyboards that still had grooves in the keys for your fingers make my sound editing go way faster than the newer flatter keyboards. So much so that when I broke my old one, I bought a new standard issue one and took off all the keys and replaced them with the colorful pro tools keyboard shortcut keys and I've done this twice now since 2005. I find my sense memory of what key is where is dependent upon the grooves and the feel of the older keys and the new ones slow me down a lot!!!UPDATE: The keyboard I use and love is an oldschool (from around 2002-2003) Macally iKey with the Pro Tools colored keys. It works like a charm for me and can get around shortcuts pretty fast. It's fairly silent and I've recorded it many times for generic typing SFX as well!------Grub is preventing me from booting from usb to install DebianAs @jdwolf already commented...You may actually be booting from USB after all. If the system is booting in UEFI mode, there should be an UEFI bootloader at EFIbootbootx64.efi on the USB stick. On Linux installation media, this UEFI bootloader is often an UEFI version of GRUB.If unetbootin changed the layout of the boot files without also adjusting the configuration of the UEFI bootloader (which might be found at EFIbootbootx64.cfg or EFIbootgrub.cfg), then your boot attempt from the USB media might end up with an UEFI GRUB with no valid configuration.It is also possible that your UEFI implementation may be buggy. Some UEFI versions of GRUB were quite sensitive to UEFI implementation details - I think this has been improving lately, as the GRUB developers receive bug reports and other experience on various UEFI implementations.With modern distributions, unetbootin and similar tools could be unnecessary for preparing an installation USB media: many installation ISOs come now prepared with isohybrid (see here) or similar tools so that you can simply write the ISO to the USB media using dd or a similar tool and have it just work. This way both the legacy BIOS and UEFI bootloaders on the installation media should be using the configuration that the distribution maintainers have actually tested, rather than a configuration built by unetbootin using heuristics.------linux - two keyboards one computer different keys sentDo you really need two keyboards? If you always have your Num-Lock key either on or off, you can do what you want with just a single keyboard... This method may(?) work with two keyboards if you prefer. Using a single keyboard may be faster than having to move you hand(s) from one keyboard to the other. You can use xbindkeys which allows you to launch shell commands with your keyboard or mouse under the X Window System. The particular feature of xbindkeys which can be used here is that it responds to the state of the Num-Lock key. Lets assume that in your normal typing mode you have Num-Lock on... When you turn Num-Lock off, every key is seen differently by xbindkeys. So, you can assign macros to any individual key you like, eg. I use To do this, using a single keyboard, I need to press three keysFor two keyboards, it would only need that you press the Numlock / key. Aside from the Numeric-keypad keys, the other keys function normally whether Numlock is on or off. So if you don't typically use the keypad at all, then it may be enough to use xbindkeys and assign 16 shortcut keys for Numlock off, and another 16 for Numlock on. Otherwise you have all keys available as new shortcuts.. (for Ubuntu): sudo apt-get install xbindkeys xbindkeys-config------Why is my keyboard acting like the Ctrl key is pressed when I hit an F key?I have run into 2 extremely similar problems which roughly fit this description. After a year of living with them, I finally figured out how to fix them.(1) Press Ctrl-Shift a few times. This seems to fix it for me. When I hit ctrl-c, it no longer puts the cents symbol. Pressing ctrl alone and shift alone may not be sufficient to fix this.This problem, bafflingly, is always specific to the application/window. Quitting and restarting each app fixes it for that app. I have this problem both with the Advantage2 Kinesis and Advantage Kinesys. It seems to be specific to my work machine and never my home machine. Oddly, it happens even when I remote desktop in from home to work. It may be Windows 7 specific. I read about a Advantage1-Windows7 problem which is fixed by either a bios change (disable usb 3 or turn on usb debug mode), a usb-to-ps2 dongle (plug usb keyboard into ps2 port) or an Advantage2 but I think this is a different problem because my Advantage2 (LF) has the same problem.(2) Press Alt-Shift once. This is the default hotkey to switch keyboard input languages in Windows. See the control panel. Every once in a while, I accidentally hit alt-shift as I type a hotkey and trigger this. When I hit shift-3, it no longer puts "/". If you disable all the alternate keyboard layouts, this problem goes away------What are the hotkeys for mstsc.exe?This is the list of shortcuts in the Win7RC MSTSC help (these work whatever the setting of "apply windows key combinations)":AltPage Up: Move between programs from left to right.AltPage Down: Move between programs from right to left.AltInsert: Cycle through programs in the order that they were started in.AltHome: Display the Start menu.CtrlAltBreak: Switch between a window and full screen.CtrlAltEnd: Display the Windows Security dialog box.AltDelete: Display the system menu.CtrlAltMinus Sign (-) on the numeric keypad: Place a copy of the active window, within the client, on the Terminal server clipboard (provides the same functionality as pressing AltPrtScn on a local computer).CtrlAltPlus Sign () on the numeric keypad: Place a copy of the entire client window area on the Terminal server clipboard (provides the same functionality as pressing PrtScn on a local computer).CtrlAltRight Arrow: Tab out of the Remote Desktop controls to a control in the host program (for example, a button or a text box). Useful when the Remote Desktop controls are embedded in another (host) program.CtrlAltLeft Arrow: Tab out of the Remote Desktop controls to a control in the host program (for example, a button or a text box). Useful when the Remote Desktop controls are embedded in another (host) program

PS2 is an original way of connecting keyoards (and mice) to comuters, efore USB was created. Aart from the differences I will mention in this answer, a PS2 and USB connected keyoard will ehave almost entirely the same while gaming.PS2 uses a different rotocol in dealing with actual user inut. When the state of a PS2 device changes (e.g. a key is ressedeleased), the rotocol interruts the current task of the CPU and the system immediately starts dealing with the new state. USB on the other hand gets olled, which means the comuter kees asking multile times a second the inut device for its current state.So in the end, no, using PS2 has no enefits for gaming, excet for the N-key-rollover that could e useful in some secial cases. While connecting your keyoard using PS2 won't harm your game exeriences either, it is roaly the easiest to just stick to the rotocol everyone uses: USB.There are other reasons not mentioned in this answer for using PS2, ut these don't make any difference on gaming. For more information I suggest the sources of this answer:Wikiedia - htts:en.wikiedia.orgwikiPS2_ort Related QuestionsSend Ctrl-Alt-Del to nested RDP sessionI found a way to make this work.

Open it up and removed the keyboard controller PCB.Figure 1. (1) The PCB and contacts. (2) and (3) the matrix keyboard which you'll be dumping.I used the controller in the photo and the contacts were covered with some kind of coating which wouldn't take solder. It scraped off quite easily and I soldered the wires on.I developed this technique to make a foot-operated switchboard for controlling a slide show while playing the guitar. I stopped testing when I found the combinations I wanted.Table 1. The Lenovo keyboard matrix.You could wire several of these controllers to send the key signals '1', '2', '3', etc., to a program or even to WordPad set to a very large font. You would see the keypress sequence on the screen as '213' or similar but if someone holds down the button you might get '21111113'------How to swap the fn use of Function keys on a *generic* Keyboard in LinuxFn is not a normal keyboard key, such as the modifiers Ctrl, Shift and AltGr. For a standard modifier key, the microcontroller inside the keyboard sends a scancode for the modifier itself, which is then interpreted by the operating system and combined with other simultaneous key-presses. The Fn key is a form of meta-modifier key, in that it causes the operating system to see altered scancodes when other keys on the keyboard are pressed. This allows the keyboard to directly emulate a full-sized keyboard, so the operating system can use standard keymaps designed for a full-sized keyboard. However, because the operating system has no notion of the Fn key, the key can not normally be remapped in software, unlike all other standard keyboard keys.While it is most common for the Fn key processing to happen directly in the keyboard micro-controller, offering no knowledge to the main computer of whether the Fn key was pressed, at least one manufacturer, Lenovo, performs this mapping in BIOS running on the main CPU. This allows remapping the Fn key by modifying the BIOS interrupt handler.Source: http://en.wikipedia.org/wiki/Fn_key#Technical_detailsAnswer to the question: Remapping not possible via operating system but only via BIOS (in some cases)------Restoring Windows 7 without Disks - What should I Know?Turn on your PC or restart it if it's already on.Watch for a "entering setup" message in the first few seconds after turning on your computer. This message varies greatly from computer to computer and also includes the key or keys you need to press to enter BIOS.Here are some common ways you might see this BIOS access message:Quickly press the key or keys instructed by the previous message to get into BIOS.Note: You may need to press the BIOS access key several times to enter BIOS. Don't hold the key down or press it too many times or your system may error or lock up. If that happens, just restart and try again.When you enter BIOS you can navigate the BIOS menu using the keys of your keyboard, it will look something like this:http://0.tqn.com/d/pcsupport/1/0/H/2/-/-/biosmainmenu.jpgJust go to the Boot Menu and locate the option for changing the boot order.

Make sure you can connect to it with the official LEGO Software programming environment, NXT-G, and that the computer connection will show up when you go to Bluetooth > Connections.Next, you'll want to create a simple program in NXT-G and download it to your NXT. It should basically send a Bluetooth message to the computer, using Mailbox #1 and a number variable containing the value of the key pressed. If you need help with this part, I can provide detailed steps.Finally, you'll want to use a program called InstantEXE 3.0 (the free version works!) to receive the Bluetooth signal and use the command "Keys" to simulate the key or key sequence that you want to be triggered when the button is pressed. You can expand this with your sensors, e.g. when touch sensor #1 is pressed send it with a value and intercept this on the computer, using InstantEXE 3.0 to convert it into a keysequence. If you need help with this part, I can provide detailed steps and/or a sample program for you to use. You could use some basic labels like the following script::LeftKeys "L":CenterKeys "C":RightKeys "R"------Alert window, navigating to the right buttonYou can activate Cancel by pressing ESC. All of the Mac OS X dialogs, which has a properly associated Cancel action could be closed with ESC key (with some exceptions).So, you have ENTER for focused (default) action, ESCAPE for cancel and SPACE for alternative action (if any), which is enough in most of the cases. The only problem I see here is discoverability, but once you will discover that it will work in any app and dialog.So, actually, it's even more user-friendly (you'll have to press just one key to choose an option).Rationale I see behind this, is that it's better to think about the dialog, figure out how user will use it and why he or she even needs it. I can imagine a 5 buttons dialog on Windows just because it's possible to navigate between options with keyboard, but think it's almost impossible to get such dialog in OS X, even if you got it it seems like it will be too complicated to choose an option quickly, so you probably have to use mouse.Concerning an ability to use keyboard, I think, it's a plus, especially, for situations caused by other keyboard actions: you will be able to not change the input device, which could be annoying------A good use case for Postgres JSONB?This is indeed a reasonable case for storing object-like or key/value data, and representing it as JSON in jsonb fields in PostgreSQL is a reasonable way to do that.In general it's time to consider hstore, xml, jsonb, etc when you're starting to look at alternatives like EAV or wide tables where the app adds columns dynamically. jsonb is basically the new hstore with a more standard way of representing its data and with nesting capabilities, so it's preferable most of the time.Static tables for different kinds of thing, with parent tables for more general categories of thing, still make sense if the things being tracked are (a) fairly static and not user-defined, and (b) not excessively numerous. That does not sound like the case here.I still recommend keeping attributes as regular columns where:You can define a unique constraint - or rather, unique index - over an expression that queries the json field. It's just often cleaner to have them separate. Similarly expression indexes can help with oft-queried fields you want to keep part of the json object. It's really the first point that's the most important, as RI constraints cannot reference the value of a json object key------How many different modifier keys can we have on a keyboard?I'm not sure if I completely understand your question but, without n-key rollover using PS/2 you can only have 4 modifier keys per keyboard.Excerpt from this article.PS/2 vs USB Technical LimitationsKeep the following in mind if you have an n-key rollover keyboard that can be hooked up to your computer through either USB or a PS/2 port:USB protocol limitation - A max of 10 simultaneous key presses are recognized, 6 non-modifier keys ('w', 'a', 's', 'd', etc) 4 modifier keys (Shift, Caps, Ctrl, etc). Although you are limited to 6 regular keys you are still guaranteed that any combination of keys will be recognized properly if you have an n-key rollover keyboard. I would guess that most people would not need support for more keys than this. I would also guess that the 6 key limit may have had something to do with braille input requirements rather than someone choosing an arbitrary limit (although that doesn't explain why the limit exists in the first place). PS/2 - There are no limitations when using a PS/2 connection with your keyboard. You will truly get full n-key rollover support.So using 2 standard keyboards without without PS/2, I think that you could have a maximum of 8 modifier keys.

Not a suer user, ut may I add, aout the "keyoard rolem" for such a situation, that the slow resonse to key-ins could mean a CPU that is overwhelmed with tasks, ossily slowed greatly y a adly fragmented HDD.Once you use a USB keyoard to gain access, suggest you defragment (everything: files, free sace, the age file, etc.), using a (free) utility like "ccleaner" if need e. Then exlore (task manager) to see if you've got dozens of unnecessary tasks running (automatically) and trim them down.These measures may e esecially imortant if you are using media center to record large files (such as videos) on a large HDD that has ecome adly fragmented over time. Just a thought Related QuestionsDoes the cv2.waitKey argument determine the frame-rate while caturing a video?waitKey actually determines how much time your rogram "waits" for a key eing ressed y the user efore going on with the rest of the rogram.It is usually indeed used to "simulate" a given frame rate etween two successive frames to e dislayed. However, if your image rocessing ste takes 1 second to e executed, your video will e dislayed in slow motion anyway.You can also use it with the argument 0 (or no argument at all as it is the default) if you want your rogram to dislay the same frame until you ress any key. That last use case is sometimes useful when you want to carefully oserve a series of following frames without saving them on your hard drive------AltU started producing signSince you stated that you use Polish Programmer keyboard layout, it is by default that AltGrU produces the euro sign. Source: & for why it changed, you might have pressed Left Alt Shift or other combination that changed your input language accidentally and reset it to the default input for AltGrU instead of your custom shortcut. Or as others stated it might have been a system update. I guess you should just choose a shortcut that does not conflict with those already assigned by the system, just to be safe that it won't be reset. A tool like ActiveHotkey( would help view those already assigned------How does the ZX80 keyboard avoid ghosting and masking?That circuit uses some address lines to enable keyboard reading. Some other address lines (not part of the enable circuit) determine which columns (note the s) are read: a low address line can, via a keyboard switch, pull one of the inputs of IC10 low. This depends on the property of LS TTL inputs that a floating input is seen as high.The diodes in the circuit are needed to prevent that pressed keys could connect an address line to another address line, which would not be a good idea. They are not there to prevent ghosting/masking. The ZX80 had a membrane keyboard, it was hard enough to press one key, multi key press detection as not a feature of this beast.------Securely making an SSH connection from a public computerWhy don't you make your debian computer to require only public and private keys instead of requiring for a password? You can change that setting on the sshd_config file. But before you do that you just have to generate the keys and install them on your server with ssh-copy-keys. After going through this process nobody would be able to even try to guess an user and password because the only way to access it is by having the key and if you want it even more secure you need to provide a passphrase when creating the keys.I do this also when I'm lazy and I don't want to type my password every time that I want to log into my server.------Emit region-neutral keyboard signalsNo. There is no such facility.If you take a German keyboard and plug it into a US configured computer the key layout will be wrong. You have to tell the computer that you're using a German keyboard.Keyboards don't know what is printed on the keycaps. All they understand is where the buttons are physically located.The same with the Arduino. It's sending the keypresses that correspond to the keyboard layout of a US keyboard, and you have to tell the computer that you're using a US keyboard - because that is effectively what you are using.If you want to change the keyboard map the Arduino uses you will have to manually modify the Keyboard library (file Keyboard.cpp, array _asciimap128).------Asus ROG Zephyrus Keyboard Backlight not working duplicateI can confirm the Zephyrus keyword isn't working for 17.04I had the same problem, and I was able to solve it, but I'm using Gentoo with 4.12-8 vanilla sources.My solution was adding blacklisting asus-nb-wmi, for that, you need the following text inside /etc/modprobe.d/blacklist.conf fileI hope it works! The problem seems to be related because asus-nb-wmi adds one fake (or wrong detected) keyboard device, and hid_asus also adds other device, so desktops seems to be using the first one which is wrong. blacklisting will avoid the bad one and keep the other correctly.This solution will add suspend, airplane mode, keyboard lights, screen lights, screen keys and volume. That doesn't fix the numeric keyboard.Regards.------Something denser than lead but with lead like properties?Here's a link to a listing of the elements in the periodic table sorted by density. The density of lead is 11.35 g/cm^3. If you wanted higher density, no toxicity and to really let your pinky live in style, then gold with a density of 19.32 would be a possibility. Other relatively available elements that are denser than lead and without toxicity concerns include palladium (12.02), rhodium (12.41), tungsten (19.35) and platinum (21.45). If you're willing to be a bit less dense than lead, then you can reduce price by using copper (8.96), molybdenum (10.22) or silver (10.5). Alloys of some of these elements are also available at high density, but the cost (due to fabrication costs) is likely to be as high or higher than that the element itself------Does somebody knows why the Apple-key has been renamed Command key?The symbol, called a Gorgon loop, has been in use since the first Mac keyboard. The key, called the Apple Key, or Open Apple Key, is referred to most commonly as the 'Command Key' - similar to the Windows Key on pretty much all other keyboards. It is used to issue keyboard commands, hence its name.They never changed the name, although some keyboards did have an actual Apple logo on the key. 'Cmd' is semantically easier than just a symbol, especially when trying to explain to a Windows-convert. Lastly, with the switch to Intel processors, its possible to run other OSes on Mac hardware. There is no 'Apple' key in Windows in Linux, but the key still has functionality------Windows 8.1 - Group Policy Settings set, but not executet when offlineAfter some more testing, finaly the settings are still beeing applied offline.The problem seems to be to "DOmain Guest" Group.

In days of old type setting for a printing press was easily jammed by type setters that were too fast, the keyboard layout was changed to make it more difficult to type fast. So it is intentionally designed to slow your typing. A newer design known as the Dvorak keyboard layout - Wikipedia named after the creator is not linear either, but it is optimized for fast typing. A few people use it and swear it is much better, but it never really caught on enough to become the standard. You can still purchase a Dvorak keyboard. Why don't we have continuous keys on the keyboard?Why are computer keyboard keys not linear?------Cheapest, simplest way to implement a Bluetooth keyboard/mouse?You'll find this is often the case, when you try to build something from off the shelf parts that duplicates an existing product, almost always the parts alone will cost more than the existing product.

I solved my problem successfully by upgrading from El Capitan Beta to the Stable release 10.11.4. I did this by downloading the installer from the App Store application (can be found in the Purchases tab), and running it on my PC. After selecting the drive on which the current OS X was installed, I waited around 30 minutes for the installation to complete. It was completed and I didn't lose any of my data.Once I logged back in, I clicked on the Bluetooth icon while holding alt and shift, clicked on Debug and Remove all devices. After that, I reconnected my keyboard and it worked fine

You can try pressing the Win key a few times to see if the issues goes away.------Space as modifier key XKBI think you're going to have immense difficulty getting the 'tap to space; hold to shift' behavior.That said, you can use xkbcomp :0.0 to dump the current keymap from the server to a file server-0_0.xkb, and I think I see an easy way to get the space bar to function as as modifier:Try replacing space with Mod5 (or whichever modifier key makes most sense), and then add a new modifier_map line:This is untested, but it feels right.I don't know how you'll get a plain old space though. I'd suggest mapping it to another key entirely------Any cool programs that take advantage of Scroll Lock?Excel uses it (and I think Excel is cool)If you hit scroll lock then move around the sheet using the usual page up / down or arrow keys then you see different parts of the sheet, but the active cell remains unchanged.This is great when troubleshooting or checking formulas and results, as an easy way to move around your data while still staying in one place, which is then easier to return to (eg press scroll lock again to turn it off, press right arrow , left arrow and Excel will bring the active cell back into the visible window).------Is there a word for (computer) keyboard keys that have a valley in them, like caps lock?From reading the term step seems promising, so perhaps stepped keycaps or keycaps with a step?I don't know how "official" the term is but that website has an amazing amount of information on keyboards and keycaps and seems as authoritative as I can find.And from same page ...It usually occupies a prominent place between Tab, Shift and A, and is easily engaged by mistake when reaching for A. To avoid this mistake, many keyboards have a stepped caps lock keycap that places a gap between caps lock and the adjacent letter key.------My keyboard is typing by itself, could there be a ghost in it?The "could there be a ghost in it" really got me laughing, What I can tell you is this, from my years of experience it's most likely a faulty keyboard which needs replacement.But in order to be really sure, put your PC in airplane mode(disconnect from the internet), this is to be sure that a hacker/script isn't controlling your PC.watch it for a couple of minutes and see if it continues to exhibit the same behavior if it doesn't, Kindly go to your nearest PC Engineer and get your keyboard fixed or replaced. Good luck.------PROGRAMMING KEYS Microsoft Ergonomic Keyboard 4000 / Mac Mini OS X 10.9.5Adobe apps have their own Keyboard Shortcuts setup, in the Edit menu.I don't have InDesign, only Photoshop, but this is what it looks like in thereIt's in Layer > Arrange you need to do a lot of scrolling to get thereAfter commentsIt may not be possible to assign a single-key shortcut in Adobe, it may always need to include Cmdhowever, you could perhaps do the equivalent inSystem Prefs > Keyboard > Keyboard > App Shortcutsby assigning each one to 'All Applications' - which will then work in any app that actually has that precisely-worded command------How can I type special symbols on my Android device like or as a regular character?These are actually Unicode characters you can easily reproduce on your computer:How can I get WHITE SMILING FACE (U263A) with the keyboard?The Android platform supports unicode and all its characters, however the soft keyboard that comes with your Android ROM probably won't carry all your desired symbols.When long clicking on some symbols/characters on your soft keyboard you will see the key pop-up expanding to give you an additional choice of symbols, then drag and release your finger to print them.Installing some 3rd party keyboards (such as GO-Keyboard) will give you access to more symbols.------Microsoft Keyboard Layout Creator, buggy mapping on right altThis may not exactly be what you're looking to accomplish but I believe the US - International keyboard layout already has the Swedish characters that you need. They're made available through AltGr (i.e. the right Alt key or CtrlAlt) shortcuts.Some CtrlAlt shortcuts may trigger other action on certain programs.For instance CtrlAltp would open the Print dialog in Notepad.You can check what characters are available to you using Microsoft Keyboard Layout Creator by loading your existing keyboard profile through File Load Existing Keyboard... and checking the AltCtrl (AltGr) shift state.------How can laptop keyboard keys be removed and replaced?You want to google for the service guide. I googled "HP dv2500 service guide" and the first hit is a PDF describing how to disassemble the laptop and replace parts. Once you've got the keyboard out you may find it easier to clean.If the keyboard is beyond repair, check if you can get replacements on ebay.I have performed a similar repair on a Dell laptop, and it's really quite easy when you've got the service guide. Individual keys could be popped off with a little force from underneath and reattached by pressing down hard until it clicks------Mac Power via Keyboard Shortcut?There are multiple ways to do that.You could use an Arduino Leonardo as a keyboard, then send a shortcut command to shut down or sleep the computer. You can edit these from System Preferences>Keyboard>Shorcuts>Services.The keycode 0x66 does not work for mac, but may for other operating systems sourceYou could write a small program (I'd do it in Python) which communicates with the Arduino over the serial port and shuts down the Mac if the Arduino wants it to.You could sacrifice an USB keyboard and use a relay to "press" the power key.------Can I install OS X lion on a disk that is OS X Extended Journaled encrypted?I am guessing here:The disk may have to be unlocked first. It will either prompt you to unlock it during the installation, or you may have to do it by accessing Disk Utility before the install process (Utility menu on the 1st or 2nd screen of the install).Another way of doing the same thing is not to have an encrypted disk, and install Lion. After the installation completes, encrypt the disk through System Preferences -> Security. It will prompt you to restart and then it will begin encrypting the whole disk, even as you use it. Great feature------Bluetooth not detected with rfkill list on dell xps from fresh install duplicateFrom: Turn Bluetooth on or offYou can turn Bluetooth on to connect to other Bluetooth devices, or turn it off to conserve power. To turn Bluetooth on:Open the Activities overview and start typing Bluetooth.Click on Bluetooth to open the panel.Set the switch at the top to ON.Many laptop computers have a hardware switch or key combination to turn Bluetooth on and off. Look for a switch on your computer or a key on your keyboard. The keyboard key is often accessed with the help of the Fn key.From this answer:You can try:------Pop-up appears when keeping a key pressed for more than a second while playing Diablo 3 on OS XThis question belongs on but what you're actually seeing here is that the text entry system that Diablo uses is "well-behaved". (FireFox's text entry system probably isn't, on account of being cross-platform, and Terminal isn't for similar reasons.)This question has the opposite problem, but should be illuminating. stackexchange.com/questions/35576Edit: After a review of the screen shots it appears it might not be as well-behaved as I thought, if it happens outside of areas dedicated for text entry.From the linked question; fix by opening Terminal.app and running the following command:------Keyboard Input over MS Remote DesktopAlright, so get this: Microsoft Office has its own language settings, distinct from Windows, and these language settings influence the languages which appear in the language bar.Somehow, the language bar was picking English (Canada) as the current language, and this somehow resulted in the strange keyboard inputs. (I live in Canada, and our English keyboards are identical to those found in the States, so I don't know why the keys would be so badly remapped, but I digress...)Run any Office application, bring up Options under the File page, and remove unwanted languages there. This, hopefully, addresses the problem------New keyboard for programming wanted has a number of videos and articles you may find helpful in making a decision.I would suggest a keyboard with Cherry Speed Silver switches in your case for their shorter travel, e.g.: amazon.com/Mechanical-Keyboard-Switches-Lighting-Stealth/dp/B07VXRXMHF/ amazon.com/CORSAIR-Mechanical-Keyboard-Backlit-Resistant/dp/B07QBD76TX------Offline RSA strong prime test similar to Phuctor?How about the other keys we found? Some of them have valid self-signatures. As in, a naive user querying SKS for an email address without regard to fingerprint will be shown one of these as the top search result. And, for all we know, they will display a valid fingerprint on some broken PGP-compatible system.If, as Mr. Bck would have us believe, we had found that 'cosmic rays' or 'disk corruption' are able to generate valid PGP key-self-signatures - we'd be collecting the gold at Stockholm for this find, rather than settling for this small change------Ubuntu 14.04 doesn't wake up after screen is locked and blankI had similar issues with Ubuntu 14.04 and 16.04 more recently.After struggling for a while, I found that disabling USB auto suspend, solved (worked around) the problem.This feature is a part of usbcore which is compiled in the kernel in Ubuntu.From the /etc/default/grub file and change the GRUB_CMDLINE_LINUX_DEFAULT line to add the usbcore.autosuspend-1 option:Note that quit splash were already present options. So keep other options you have too.After save the file, update grub:And reboot.Now check autosuspend value:And it should display -1.

Why are computer keyboard keys printed in Uppercase? [duplicate]I believe it's partly alexeypegov's answer of distinctiveness, but also historical reasons. The first typewriters, which also had the first QWERTY keyboard, only supported upper case letters------What combination of Keys on the Computer Keyboard make a musical note symbol?Turn on your number lock and still use your keypad. With number lock off they can act as navigation hot-keys as you saw. I use alt codes on a daily basis and am irritated when I accidentally turn it off. I am entering the alt code such as 0176 for and my browser thinks I am talking to it. According to your results you are using the number pad. It just needs to get turned on. You can usually set number lock on through your BIOS. This will turn it on automatically when Windows starts. Pressing delete or F1 lets you into your BIOS,------What's the best way to clean a computer keyboard?pop each key out, then use a paint brush to dust the base. use an all purpose cleaner to clean each key. do not open the whole keyboard as it will be difficult to put it back together if this is your first time to do it.------Who decided where the keys on a computer keyboard would be? and Why did they decide the way they did?They used to have them in alphabetical order but apparently, when people were doing typewriting work, they were doing it too quickly so they mixed the letters on the keyboard up to make it more complicated and difficult! It's been like this since. We call it the qwerty keyboard because those are the first letters on the keyboard! qwerty!------computer keyboard questions, which is best?I have a Logitech G15 Refresh Keyboard. I would and always highly recommend it. It retails at a very good price, I paid $130 NZD for it and had well been worth the money. I would reccommend and keyboard from the Logitech G series. Have a quick look at their website.

The Logitech MX Keys is a wireless keyoard that uses either Bluetooth LE (low energy) or the Logitech Unifying wireless receiver. The USB cale is for charging only. So, excluding the USB connection from your question, this comes down to the following ossiilities:You might have interference issues with your BT (AirPort card) on your Mac. To isolate, remove the dock and try airing. If that doesnt work, try airing with the USB receiver. But to get a solid diagnosis of your BT adater, try a different device to ensure it connects as it should As for your keyoard, try airing with another comuter. If the symtoms ersist, its the keyoard and it should e returned. If they dont, then youve definitely narrowed it down to your Mac Related QuestionsBedtime remote tied to wrist to muteshut down comuterAlthough not the remote you descried, it's ossile to turn off (almost) any c after a secified amount of time. This will ro you of your choice on when to turn it off, ut if you always turn it off after aout the same amount of time it's a retty viale technique.On windows:Press the windows-key R, and tye shutdown -s -t numerofseconds.

Again, 1800 is the numer of seconds until shutdown.On OS-X:Multile stes are involved in getting OS-X to do this.But in all seriousness, after launching a consoleterminal you should e ale to use the linux-method.------Why is 'shift space' not popularly used?It's not used because of unintended consequences.If I'm typing something and want to write THE END, remembering to let go of Shift in the middle or after each word becomes a huge burden. Even understanding why the computer didn't type the letters I wanted is confusing. In the case of Chrome the space bar isn't being used for the " " character, but as a directional key (like the arrow keys). In that case using shift space makes some conceptual sense to reverse the direction. You may be able to make a decent argument for shift space being used for _ in programming IDE's, as there is likely less need to type in all caps. Even then, it would have to be an option that could be disabled as required by the language being used------Can I use a foot pedal to send mouse clicks and/or modifier keys ergonomically?RSI refers to Repetitive Stress Injury. You see the word 'repetitive' there? So, it has to come with anything that you repeatedly do. No matter wrist, ankle, elbow, knee! But then, if you think a bit more, the strength we have in our extremities is different from each other. Said that, by nature, legs are stronger than hands. Extending this further, toes are stronger than fingers, knee ...than elbow, and hip joint ...than shoulder. The same goes true in case of foreleg vs forearm, thighs vs biceps and so ankle vs wrist. I don't say that using ankles won't cause RSI), BUT as compared to wrists, your ankles are a bit stronger so they'll take longer time to get affected. But RSI -repetitive...so doing it again and again won't spare you at all!------Mac often perceives left-click on Magic Mouse as right-clickI randomly noticed that a three-finger-tap on the built-in trackpad would not pull up the dictionary entry for the selected word (like it used to).I navigated to:This was very strange, because this feature has always been enabled, and I never disabled it. I enabled this checkbox, and the "look-up" feature now worked.But, this immediately made my computer stop perceiving all right-clicks (i.e., right-clicks on my mouse were always perceived as left-clicks).So, I navigated to:After doing this, my computer has not perceived a left-click as a right-click again.I still have no clue what caused the issue, or why doing the above solved it, especially considering that, for good measure, I had already previously deleted the com.apple.AppleMultitouchTrackpad.plist and com.apple.driver.AppleBluetoothMultitouch.trackpad.plist preference files------Why don't gaming keyboards typically work with KVM switches?The USB keyboard protocol is limited to 6 keys pressed simultaneously 3 modifier keys. To bypass this limitation, some keyboards report to computer as a USB hub with multiple keyboards connected to it.If your KVM switch was just directly passing through its USB port to the active computer, it would work fine, but this approach has two disadvantages:To solve these problems, switches take over keyboard communication and pretend to be a permanently connected keyboard for each computer. Keystrokes are passed through to active computer or intercepted if they're recognized by the KVM as a special command.For this feature to work, the connected device must actually be a keyboard - KVM doesn't implement complete USB protocol including hub support. So if the keyboard reports as a hub, the KVM may not know what to do with it.------How can I configure the buttons on a Corsair gaming mouse?Unfortunately, Corsair doesn't seem to want to support linux at all. However, there are a couple of work arounds. Although it's important to note that I haven't tested these solutions myself. In addition, my M95 doesn't use the config that's on it when I'm on Linux, but it works on Windows.You could use VirtualBox and a Windows virtual machine to configure the mouse. Not ideal, but it works.Note: A second mouse is recommended.While that's downloading, install VirtualBox:sudo apt-get install virtualboxAdd your user to the "vboxusers" group (very important):sudo useradd -G vboxusers usernameLog out, and back in for this to take effect (also very important).Note: You will probably want to have a second mouse on hand.Alternatively, you could just boot into Windows and make your changes there------How does YubiKey protects it's secret key?If it is plugged into an infected computer, wouldn't the secret key be compromised?The yubikey stores the key on its internal storage media -- the exact mechanism varies depending on the type of key. When yubikey is plugged into a computer, it is recognized as a USB keyboard. Pressing the sole button on the yubikey will send a string of characters containing your one-time password, just as if they were typed via a USB keyboard. The manufacturer assures that the secret key used to generate one-time passwords can never be read off of the device, regardless of the software installed on the computer it's plugged into.Also, is it possible for a computer virus to "infect" a YubiKey?Everything is possible, but would be very hard considering the limited functionality of a yubikey------Multiple Screens, Multiple OSMultiple OS's from one console...A) virtualized. You can run sessions full screen, looks seamless. You thought he wasn't doing that, though, and you mentioned a Mac, so unless he was running a Mac it's probably not it (virtualizing it is possible, but can be a royal PITA and is against Apple's licensing)B) KVM-multiple systems were running "somewhere" and the KVM is either hooked up physically (so each of those systems were, for example, under the desk) or over the network as an ethernet KVM. Keyboard hotswitches could be used to switch among systems.C) remote control software. VNC, Remote desktop, etc. running as fullscreen sessions give the illusion of multiple systems on one desktop.Those are the ways I know of that one system can "run" multiple platforms/OS's at once------Connecting two computers possible RDC duplicateTo turn on Remote Desktop, press start and go to the Control Panel. Click on System and on the left will be link labelled Remote settings. Click that and a new windows will appear with the title System Properties. On the 'Remote' tab, there's a header 'Remote Desktop' with three radio buttons. If you are set-up on a domain, you can select 'Allow connections only from computers running Remote Desktop with Network Level Authentication', else click to 'Allow connections from computers running any version of Remote Desktop'. Follow this procedure for both computers.On one computer, open up a command-prompt and type ipconfig to find your IP (should be something like 192.168.x.y).On the other, press WinR and type mstsc. Enter the IP address of the other computer and log in------android special characters keyboardYou might want to take a look at Hacker's Keyboard:A full 5-row keyboard including arrow and Esc/Ctrl keys, intended for tablets.Are you missing the key layout you're used to from your computer? This keyboard has separate number keys, punctuation in the usual places, and arrow keys. It is based on the AOSP Gingerbread soft keyboard, so it supports multitouch for the modifier keys. It supports a bunch of keyboard layouts -- though I'm not sure about the "special characters" being inserted using alt sequences.If you're mainly interested in being able to insert special characters (and don't care whether they are bound to alt-sequences or selectable by other means), I'd suggest to search the playstore for "charmap". This will yield about 10 results, the topmost of them would match your needs.------Cursor jumps frequently to top leftIf it happens in both windows & linux on the same hardware, then try a "hardware test" (provided by the hardware manufacturer, usually run from windows).And/or there's some "usability" setting, configured to a slightly different threshold between the two OS, e.g., "disable touchpad while typing" (just guessing), perhaps enabled Windows & disabled in linux. Or maybe one of these settings are configured to a different sensitivity level. (All this assumes it's not a hardware problem, but rather how your hands may be triggering the mouse to jump to the corner of the screen)Also, fwiw, 16.04 is pretty old (released 04/2016); perhaps try 17.10 (released 10/2017) and see if that improves the situation. You can try a newer Ubuntu directly via a bootable USB, rather than re-installing. (Maybe try kubuntu, too, trying to tweak keyboard/mouse/touchpad settings.).------My MBP keeps freezingIt is unclear to me but did you replace the keyboard with the defective "w" or does the replacement keyboard have the "w" issue?The reason being, holding down a key, any key, will cause strange things to happen. An electronic issue with a Mac's (or really any computer's) keyboard can cause all sorts of strange problems.Can you disconnect the keyboard and attach an external one (and will that even work?)?A Bad battery can cause issues as well. try removing the battery (if possible) and running it on power without the battery in the Mac. That works on a number of older MacBooks/Powerbooks, hopefully it will work on yours.And once the battery is out reset the SMC as per this Apple KB article apple.com/kb/HT3964.------Lost keyboard shortcut for beginning-of-line/end-of-lineThanks to the commenter Lri for pointing to this question: Commandright/left stopped working! It made me browse through the system shortcuts again, and lo and behold - CmdLeft & CmdRight were indeed in plain sight as shortcuts for "Move Left a Space" and "Move Right a Space" - I didn't even look there before because I did not use Spaces at all in Snow Leo, and so I assumed these shortcuts were inactive. Now the upgrade to Lion and Mission Control activated them, but I still had only one space so they did nothing.So it was enough to actually redefine them to something else to regain the beginning/end-of-line functionality.Sorry everyone for misleading with the wrong information (turns out I did not actually browse through all possible shortcuts...)

Any key remapping software only takes effect after it has finished booting; i.e. it will not do anything for you during the boot process when you need it.------MSI motherboard not booting to BIOSIf you have not tried it yet, you may want to reset the BIOS settings. This is usually done via a shunt on the systemboard, but I cannot tell you exactly how since I do not know the model number of your 'board.

This might help. What I would do is figure out the difference between the Norwegian layout and the default layout. According posters from the link provided, he has to press the Y key to enter z into the password field. It seems the keyboard layout reverts to default during boot.------Is Keyboard Viewer supposed to work through VNC?No.Keyboard viewer cannot be used to simulate alt, even without VNC. It shows mapping of local keyboard. Keyboard mapping in VNC protocol is a mess.Differnt VNC client won't affect sharing in any way. VNC server might collide with OSX's built-in one, but not necessarily you can configure 3rd party server to use different port------Some keys are getting hard to depress on Logitech keyboardBest bet would probably be to call Logitech support for a quick answer - other folks may have had the same issue so they may be able to provide a fix or let you know that you need a new keyboard. Either way, I'd give them a call first - 1-646-454-3200.-Alex------Intermittent keyboard and mouse failure on boot upI have exactly the same laptop and searching on the web this is what I found to solve the problem:1) Run the following command in terminal2) Locate the following section in the file:Replace it with: 3) Save the file and exit nano.4) Run the following command in terminal:5) Restart your computer.Now everything should work fine------Create keyboard shortcuts for certain symbols (like logical operators)The closest I have come to this so far is to use (on lubuntu 14.04.1) U then type the code say 00ac for which I found by using the character map.This is pretty quick way of doing it, if you know the code and remember each one. If I find another way I will update.------Why do we have 2 home keys on keyboard? closedIt's an historic reason, as you can see in this Wikipedia article:Most earlier computer keyboards had separate number keys and cursor control keys.However to reduce cost, IBM chose to combine the two in their early PC (84-key IBM PC keyboards) Num Lock would be used to choose between the two functions------Citrix ICA Client on Mac shift key doesn't work as expectedI am having the same problem. My receiver does not have the options shown on the Citrix site, so I have not found a resolution. In the meantime, my solution is to turn on "Sticky Keys" by typing 'Return' five times.
