Cross-platform remap of caps lock key

[adamgian]

kmonad looks good, or maybe: keymapper?

The stages as in my head:

• Tap 'Caps lock' (press down and release within 75? milliseconds), register as 'Esc' on the key up
• Press 'Caps lock' down for longer than the 75? milliseconds, register as a — albeit delayed — 'Ctrl' (Linux) and 'Command' (macOS) key down and pressed
• Release 'Caps look' (after having surpassed the 75? milliseconds threshold), register as 'Ctrl' (Linux) and 'Command' (macOS) key up.
• Bypass 75? millisecond threshold if another key is pressed down as well (i.e.: 'Shift' or 'C'), register as 'Ctrl'/'Command' immediately
• Bonus: 'Shift' + 'Caps lock' to toggle caps lock.
