why the keys of a keyboard are not in right order?


Depends on what you think is the "right order" The reason we have QWERTY organization goes back to early mechanical typewriters. Fast typists could easily jam up the mechanism, so the letters were rearranged to slow them down. There have been many alternatives over the years, the Dvorak layout being most commonly found. It's been shown to allow for faster typing, but it takes significant learning and finding a keyboard in that arrangement, or software that will remap the keyboard.

What product should i use to clean my laptop keyboard?
Compressed air to clean the crumbs and bits out. With the laptop turned off, turn it upside down so stuff falls out before you use compressed air. You can also remove the keyboard too but make sure you know how to put it back on. If the keys are dirty from skin oils and food, etc. use cotton swabs and rubbing alcohol. Do not use anything that leaves a residue or your keys will stick

Jank keyboard
The Jank keyboard is a musical keyboard layout for a piano designed by Paul von Jank, a Hungarian pianist and engineer, in 1882. It was designed to overcome two limitations on the traditional piano keyboard: the large-scale geometry of the keys (stretching beyond a ninth, or even an octave, can be difficult or impossible for pianists with small hands), and the fact that each scale has to be fingered differently. Instead of a single row, the Jank keyboard has an array of keys consisting of two interleaved manuals with three touch-points for every key lever, making six rows of keys. Each vertical column of three keys is a semitone away from the neighboring ones, which are in the alternate rows. Thus within each row the interval from one note to the next is a whole step. This key layout results in each chord and scale having the same shape on the keyboard with the same fingerings regardless of key, so there is no change in geometry when transposing music. Furthermore, the use of multiple rows allows the pianist to more naturally follow the contour of their hand and accounts for the different lengths of the fingers. The configuration retains the colouring of traditional keyboards (white naturals, black sharps and flats) for pedagogical purposes. For an 88-note (full size) keyboard, there would be 264 keys in total, with each note playable by three keys in vertical alignment. In the picture above, the white keys have been coloured to show how the keys are interconnected. Instead of 123 cm (48 in) the keyboard is only 89 cm (35 in) wide, and the smaller key size allows reaching wider intervals. The Jank Keyboard caused a stir at the time of its invention, in large part due to its unique look and the intelligent design behind the keyboard. American piano manufacturer Decker Brothers put the keyboard into production around 1891, and the Paul de Janko Conservatory of Music was established in New York around the same time. There was even a manual written by W. Bradley Keeler called How to Play the New Keyboard. Despite all this, the Jank keyboard never achieved wide popularity. Music educators were not convinced that the benefits of the new keyboard were enough to challenge the traditional keyboard. Both reasons left keyboard instrument manufacturers afraid to invest in a redesigned keyboard which promised to have only marginal commercial success. Many embodiments of this keyboard have appeared since its conception. Jank himself (in German patent 25852, dated 14 January 1884) originally chose a key shape which resembled the slim, black keys on the familiar piano keyboard. A year later (in German patent 32138, dated 1 July 1885) the keys became wider and shorter. Other inventors have filed patents for keyboards which are substantially similar to his design, differing most often in key shape or instrument to which those keyboards are affixed. (For example: John Trotter English Patent 3404, 4 March 1811, William A. B. Lunn devised in 1843 under the name of Arthur Wallbridge a sequential keyboard with two parallel rows of keys, each in whole tones. Miguel Theodore de Folly, 1845,Useful Registered Design Number 448 for a geometrical keyboard for the pianoforte, Gould and Marsh , Edgar , Cramer , McChesney , Stewart , Adams , Nordb , Barnett , Reuther , and Firestone .) The most recent patents are for MIDI compatible instruments.

Foreword:


Durga's K620w and K610w have always been the best-selling mechanical keyboards, and they have also gained a good reputation. The difference between these two models is that one is a full-size keyboard and the other is a small-size keyboard. The purpose of Durga is to make the mechanical Keyboard lovers can choose according to their own needs, and in order to cater to some consumers’ pursuit of RGB lighting, this model has newly launched a white light version of the product. I also started this new product Durga K620w this time. How is the performance? Let's look down together.









First of all, I have a Durga K610w at home, so this time I deliberately chose the small-sized K620w, as the new white version of the K620w, its packaging style is still the original formula, and the accessories in the box are still very rich, you can see It includes USB data cable, USB receiver extender, 2.4G wireless receiver, key clip, shaft clip, Velcro storage belt, manual and other items.
















First of all, let’s take a look at its appearance. When the keyboard light is not turned on, the new K620w still adopts a more classic color scheme. Dujia calls this color scheme fog blue, and you can see that the color of the keycap is white+ The three colors of light blue + dark blue are combined, and the frame of the keyboard is made of black metal material, which not only has a good visual effect, but also has a good touch.
















The biggest upgrade of the new product K620w this time is that it has added RGB lighting, but the lighting is not designed with color, but it can adjust a variety of lighting effects and brightness. The method is shown in the animation below, and different types of lights can be switched cyclically It should be noted that after turning on the light mode, the battery life of the keyboard will be reduced. It is reported that the Bluetooth mode connection can be used for about 360 days when the light is turned off, and the 2.4G wireless can be used for 200 days. When the light mode is turned on, it will be used according to the brightness and usage. The frequency corresponds to different battery life, the shortest is 7 days, and the longest is 90 days.
















Let’s take a look at some of its details. The white board K620w is also well done. For example, all its keys are the height of the original factory, and the characters on the keycaps are made of high-content PBT material. That is, it feels fine and comfortable in the hand, and it will not be stained with oil and the characters will not fade. The buttons in the areas that are often in contact with the fingers have been smoothed and polished.
















Let's take a look at its back. It is similar to our common keyboards, with non-slip rubber pads and angled brackets, but there are two sets of angled brackets, corresponding to different heights. In addition, a hidden storage compartment is designed on the back. It is very convenient to place the 2.4G receiver inside. Take it out when you need to use it, and put it in when you don’t need it, so as to avoid the risk of rummaging around or losing it when you need to use it.
















A USB interface and keyboard switch are designed on the top of the fuselage. The USB interface is used for daily charging or USB wired connection mode. 2.G wireless connection, Bluetooth connection, and its compatible device system is also very comprehensive, whether it is Microsoft, Apple, Android and other mainstream operating systems are all compatible, when switching modes, just press and hold the Fn key + QWER at the same time One can be switched.
















As a mechanical keyboard enthusiast, I naturally want to try different switches. I have been using custom-made silent red switches before, but this time I chose custom-made silver switches. The reason why Dujia’s K620w and K610w have been selling very well is that I think its customized switch body and support for hot-swappable design have always been the biggest selling points of this product. Consumers have a good space for subsequent DIY of the keyboard. Let me talk about my experience with its customized silver switch. It is It belongs to a linear feel switch body. In fact, the silver switch is somewhat similar to the red switch, but the stroke is shorter and the trigger is faster, so the silver switch is generally the favorite of gamers. In addition to these features, its mute effect is also very good. There is no such noise when the finger touches the buttons on the screen, and the shock absorption effect is also good.
















Combined with my actual experience, I am quite satisfied with its typing performance. For players like me who use it at home, the silver switch and the red switch I used before are more suitable for me, and its feel is more moderate. If there is Most people are professional writers who pursue that kind of crisp rhythm, so I suggest that they choose the green axis, but the sound of the green axis is relatively loud, which is not suitable for office use.









As for the game experience, if you are an enthusiast game player, I suggest you use the black switch, but most of them are not used to the black switch, I think it is quite tedious, like me playing some ordinary network For game players, such as League of Legends, it is enough to use the silver axis. In addition, it supports downloading driver software for macro settings. You only need to download a Zeus driver software from Duga official website. You can customize a variety of functions when playing games. .









Summarize:


The above is my experience evaluation of this Dujia K620w white light board. After reading it, everyone has a new understanding of this product. An easy-to-use keyboard will make you more handy in work or game experience. As a new product The Durga K620w, it can be said that this upgrade is mainly to add the lighting design, while the others still maintain the original design. After all, this product sells relatively well. The two new products launched by Durga at the end of last year are Hi Keys and K620w/K610w, they have added lighting design, it can be seen that Dujia has also begun to pay attention to RGB lighting effects.
