Use modifier to trigger remap

Modifiers can trigger a remap, but they work a little different than a normal key trigering a remap, like: Ctrl-C.

After a modifier triggers a remap will it be pressed. So it can still be used as a modifier afterwards. In other words: physically pressed modifiers will also be logically pressed. This is different from normal keys used to trigger a remap. It will look like they where never pressed.

This feature works best if modifiers on one side of the keyboard are used as modifiers, and modifiers on the other side of the keyboard are used as triggers.

Use control keys as Home and End

keymap:
  - remap:
      Ctrl_L-Ctrl_R: End
      Ctrl_R-Ctrl_L: Home

It will emit Home or End depending on which order the modifiers are pressed. The match is inexact, so pressing Shift_R-Ctrl_R-Ctrl_L will select text to the beginning of a line, because it emits: Shift_R-Home.

Use two shift keys to toggle Capslock

keymap:
  - remap:
      Shift_L-Shift_R: Capslock
      Shift_R-Shift_L: Capslock

The shift keys act as modifiers for each others.

Note: that toggling Capslock and holding either of the shift keys, will reverse the meaning of capslock, as that is what shift does. So Capslock must be toggled and the shift keys released for this remapping to work.
