What Could Have Caused the * Key on My Numeric Keypad to Stop Working in Windows 7?

This was caused y software interceting the inut on those keys.As descried in my edit to the question, it took a while efore I noticed the rolem haen again. I ruled out that it was a dirt under the key to (there was none, and ressing the sensor also had no effect, and I found that the keyad key was also doing nothing). Then I noticed something else that identified the rolem:Not long ago, I had installed Nuance Dragon Naturally Seaking (Premium) 13. 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)

v key only works with ctrl, alt or shift, not when used on its own

I quite sure it's a ad connection to the 'v' key (ad circuit line).We can have a keyoard that uses a system like this:Keys can have a null line and 2 secific ones (null, Xnormal, XCAPSEDsecondary - where X is the k letter; hysically, Xn and Xc are actually one switched y CAPS key line - they are not active in the same time ever).Taking the examle of 'v'. Just ressing it would connect Vnormal line to a null (mass line and therefore register a ress). CAPSing it would do the same y connecting Vsecondary to null.Using shift, alt or ctrl (let's say lines 1,2,3) could work with a 'v' that has a roken null connection ecause they could connect like 123-Vnormal or 123-Vsecondary, therefore not using the roken null. Transmission would work, ecause there are contacts etween 2 different lines detected.If this seems unclear, I think I could make a asic drawing.-Udate-A quick reresentation here It's a asic key ad.

I only reresented the alt, shift and ctrl contacts for one key (the low left corner).As you can see, ressing the key itself will make the R and C lines in contact.Now if either R or C link is roken, the key ress will fail to register.

But if at least one contact is working, that one will comlete a circuit if you ress Alt, Shift or Ctrl (green, yellow and red).

Why do 2 bluetooth peripherals not interfere ? (mouse and keyboard)

Basically it works because bluetooth is a network like wifi. Each device participates in that network. It's not like two walkie-talkies where one can interfere with another so operators need to take turns. (It is on the low level, but more later) Instead, it's like a wifi-network where each device participates (takes turns).Just like a wifi network, if one bluetooth device is sending a lot of data, then the other devices will need to wait. Your keyboard and mouse are less effected because they have short bursts of data. If you were to have, say a bluetooth speaker, a mouse, a keyboard, and a bluetooth hard drive all talking to the same computer, then your speaked and hard drive connections would go slower, and your mouse/keyboard would be less responsive. Keep in mind that most bluetooth setups only contain 1-2 devices. It's not really a good choice for high data throughput, ormany device connections. It is however a good choice when just sending a tiny amount of data, or when just connecting to one thing. This limitation is why bluetooth hard drives, buletooth monitors, and bluetooh printers are not very popular, while their wifi counterparts are. https://developer.bluetooth.org/TechnologyOverview/Pages/Topology.aspx Should help you understand. Keep in mind this answer is high level and doesn't really look at protocols over bluetooth, or other "extensions" that work to solve these limitations.

Grub is preventing me from booting from usb to install Debian

As @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.

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

Format keyboard keys in documents

I am assuming that your organization does not have an official style guide, or that this is a personal project. (If you are bound by a style guide, consult it.) I am also assuming that you aren't using a semantic markup already; if you're using a DTD/schema/tool/markdown that already has a notion of "keyboard input", you'd use that unless there's a good reason not to.

The Microsoft Style Guide is a common choice for software companies in my experience. This guide (4th edition, p 91) calls for capitalizing key names but not otherwise formatting them. It gives a list of "official" names of special keys. Keys that are used together are joined with ''. Correct example according to this guide: CtrlShift?.Some companies add bold face to this, e.g. CtrlShift?. In my experience this is especially common if the documentation also refers to UI elements like menu names. I think the reasoning is that "user-entered stuff" should look the same whether it's CtrlZ or File->Open.I have sometimes seen a hyphen used in place of '': Ctrl-Z, for example. I don't know the origin of this style.I recommend against using a fixed-width font. In technical writing this style is usually reserved for console output, code, code elements like function names, and sometimes environment variables -- things you would expect to see in a terminal window, error log, or editor window, in other words

Where to buy an 8 bit computer remake? closed

There are lots of 8-bit remakes in the market. Assuming you want an exact copy, the choice of makes gets smaller and smaller, if you want something that is ready to use out of the box and a complete unit (keyboard, case, storage), the choice gets even smaller.You did not write whether you care for a cycle-exact copy or a "real" 8-bit CPU (as opposed to FPGA re-makes or even software emulation). That makes your question a bit broad, and some people are a bit picky whether a Z80 computer that doesn't use the "real thing" can in fact be a Z80 computer. I am listing a number of Z80-based re-makes (software, FPGA, Z80) below:Most of the above are enthusiasts' projects with supposedly more love and entusiasm than professional entrepreneurship going into them (though all of them seem nicely engineered and are said to work perfectly). Before buying something from the linked web-shops, you might want to inquire for terms, conditions, and especially availability and lead times - Some of the offerings are only built-to-order. Most of the above platforms have forums that provide user-to-user support, and I recommend you make yourself familiar with these before buying anything. There have been failed projects in the past that collected money from buyers and showed up as unable to deliver (The infamous ZX Vega plus project needs to be mentioned here. But consider this rather an exception than the rule).

Emulating Alt ASCII codes in Linux

Not exactly what you're asking for, but similar enough that it will probably still work:Many (but not all) IME frameworks (including both ibus and fctix) on Linux support a library called m17n to provide IME's. The m17n library provides a bunch of easy to use IME's (including trivial keyboard remappings to handle various languages). One of these, simply called 'Unicode', happens to do almost exactly the same thing as alt codes. The only two differences are:So, for your example of a lowercase latin letter 'e' with an acute accent, the exact sequence for m17m's 'Unicode' IME would be Ctrl-U 0 0 e 9. Numerically, the hexadecimal number 00e9 is actually identical to the 0233 decimal value used for the equivalent Alt code with CP1252. This happens to be the case for most of the first 256 characters in Unicode, as they mostly match up with CP1252 in both order and position. This equivalency does not hold however of rhigher numbers.Other IME's provided by m17n that may be of potential interest to you include 'Latin-Post' and 'Latin-Pre' which let you add specific characters after or before a letter to produce diacritical marks or special letters (for that you would use either e' or 'e respectively), and 'RFC 1345', which uses RFC 1345 mnemonics to allow inputting a vast majority of the widely used characters from the Unicode BMP (and would use the same e' as the 'Latin-Post' method)
