  27      *
  28      * Under XOrg, I use my own mapping from QWERTY to "Workman for Programmers"
  29      * See XOrg files in ./addons/ subdirectory.
  30      *
  31      * I have to do so, because of two things:
  32      * 1) my native language is Russian, and XOrg keymap for it is based on QWERTY layout
  33      * 2) I want to have non-standart shifted keys, like $ (as normal) and @ (as shifted), or _ and -
  34      *
  35      * And even if (2) could be solved using FN* keys (but there is limit in firmware for only 32 such
  36      * keys), then (1) can't be solved at firmware level at all.
  37      *
  38      * So, I have to stick with QWERTY as my main layout + my own XOrg keyboard layout for English.
  39      * But sometimes I have to input something when XOrg is not active - for example, in Linux console,
  40      * or in firmware console (while debugging firmware), or when keyboard is connected to not my computer.
  41      *
  42      * For such cases I have Layer1 :)
  43      * // hint: switch to Layer1 is only at Layer6
