Vim leader key mapping

[pl643]

Is it possible to use capsicain to do the below mapping?

Leader Key Keyboard - inspired from the vi editor's mapleader feature

• promote tapping/demote chording
• designate a key as the "Leader" key
  • a good leader key is one that is not used frequently and easy to access:
    • ; and , are good candidates
  • tapping the leader key 2 times will produce the actual key

Mappings

• tapping the \ and the below key will change the state for the next key pressed:

  • f - ctrl

  • d - shift

  • s - alt

  • a - Winkey

  • e - sends key

  • r - return/enter

  • m - executes macro/combo - a way to send keys sequence or combo

  • v - vim layer navigation

Example key sequences

• \\ -> \
• \fa -> ctrl-a
• \da -> A
• \sa -> alt-a
• \aa -> win-a
• \mp -> sends "MySecretPassword\"
• \m1 -> sends "Ctrl-Alt-F1"
• \v -> enters vim navition layer
  • hjkl - left,down,up,right
    • e/d - home/end
    • space - page down
    • b - page up
    • 1-9 - ctrl 1-9 for chrome tabs
    • x - exits vim layer

Most of it should be possible, not very elegant but doable with deadkeys See https://github.com/cajhin/capsicain/wiki/Function%3A-deadkey%28%29

What won't work is the generic modifier combos ("leader key, F" -> Ctrl is applied to the next key). You'd have to create a rule for every specific Ctrl+key combo (like: leader Key, F, S -> ctrl+S
