NAME us_split an xkb keyboard layout ABOUT THIS PROGRAM A keyboard layout for xkb. Geared specifically towards reducing RSI, this layout is nearly identical to US-QWERTY, except there is a two-key split between the T and Y columns into which symbols from the furthest right of each row are placed. The hands can assume a more natural position two key columns wider apart (similarly as with Dvorak) and hitting Enter is not an exercise for contortionists any longer. One of the problems with US-QWERTY is that the palm of the right hand needs to move a lot -- especially bending in the wrist -- which can then lead to Repetitive Strain Injury. If you spend a lot of time typing, you should be aware of this, and should know that you might be hurting yourself with an inappropriate keyboard layout. This layout makes it easy for people to try out something new while mitigating many important issues. The changes can be seen easily at the diagrams below: Legend: A = Alt B = Backspace C = Control R = Return RC = Menu ("Right Click") S = Shift W = Super ("Windows" key) Normal US-QWERTY on 101-key ("US") keyboard: Caps F1 ...

This is analogous to them being out of the reach of the right hand in its normal position on the US QWERTY keyboard, except that this time they are accessed using the much more dexterous index finger. Additionally, they are shared with the left index finger, which as a practical outcome means that the palms of the hand need to travel less and can in fact stay in their home position most of the time, as most keys can be accessed by reaching out the fingers. Additionally, this action of reaching out the fingers is completely opposite to the movements that cause RSI, and stretches the muscle and ligaments that get damaged by non-ergonomic layouts. The symbol keys have been moved because in the US QWERTY layout they increase the distance the right palm needs to travel in order for the typist to press Backspace and Enter, which are very important and frequently typed keys. As it is, the US QWERTY layout develops a habit in its users where they jerk the palm of the right hand to the right after every finished sentence, creating a very fast pathway towards RSI. There have been attempts to solve the problem by using smaller keys for the right-hand-side symbols, as well as by making the enter key bigger. Some of them have been partly successful, however none of them was fixing the problem at its source, which is an inadequate layout. The key between the left Shift and z is the 105th key. It exists on many European keyboards and some people love it, while others hate it with passion. The author has been a member of both groups. It is mapped as a second Backspace. Caps Lock is placed where Esc was and Esc is placed where Caps Lock was. This is hardcoded for now, but might be configurable in the future. Naturally, this layout can be used in conjunction with GNOME's keyboard layout options in order to turn the Caps Lock key into another Escape, Control, or Meta key. INSTALLATION In order to install the layout in Ubuntu 10.04 and similar operating systems, use the included install.py script which will complete the whole process. You might need to execute it as a superuser. The installer should work in newer Ubuntu versions, as well. However, it has not been tested with KDE or Unity, and might not work in them. This version has only been tested with GNOME and Ubuntu 10.04. Installation usually completes without restarting the X server. In order to install on other systems, you might need to change the options of the installer. See ./install.py --help for a description of the options. For example, the xkb directory might have moved. You would search for a directory called "xkb" with the subdirectories "rules" and "symbols", among others. You might also need to change the name of the xml file. Normally, rules/evdev.xml is used on Ubuntu 10.04, but it might be rules/xfree86.xml, rules/base.xml, or rules/xorg.xml. On some systems, lst files with the same base names are used instead of xml files. Those files are not supported by the installer, however editing them by hand is fairly easy; in the !layout section you would add the line: us_split USA Split Next, you should copy the us_split file into the "symbols" subdirectory of the xkb directory. A restart of your X server might now be required. That should be all that is necessary; this installation procedure has, however, not been tested. USAGE In order to use the layout, if you are in GNOME you would use the program gnome-keyboard-properties(1) which can normally be accessed in the System menu, Preferences submenu. Alternatively, it can be started from a terminal. Once the Keyboard Properties are visible, you would select the Layouts tab, where you would then click the Add button and navigate to the By Language tab. In this tab, select English as the language and then find USA Split in the Variants dropdown. Finally, click Add. You can then select the layout from the list.
