A bit of brainstorming -- items that would help coding some experimental improvements to home-row mods with smart macros:

• a variable that contains the time (in ms) since the last keystroke, i.e. the time that the keyboard has been idle
• a macro that gets run before the rest of the key processing (i.e. before the configured action for the keypress are taken)
  • this could be just one single macro that gets run for any keystroke, i.e. $onKeyPress
  • could be used for things like resetting a timer, detecting universal chords etc.
  • could help to have something like if ($thisKeyId in ( a s d f g )) to check for multiple keys, i.e. "is this one of the HRM keys?"
• a way to bind primary and secondary scancodes to a key, but still execute a macro when it is pressed
• from such a macro:
  • a way to press/hold/release the (primary) scancode that is bound to $thisKeyId
  • a way to activate the secondary action that is bound to $thisKeyId
• a way to set secondary actions from smart macros (e.g. to deactivate/activate homerow mods in certain situations)

I believe the first item (idle timer) is not possible to do at all today. The others could be worked around with lots of macro code, but it's inconvenient.

My two relevant findings that made HRM work for me:

1. disable during fast typing: https://forum.ultimatehackingkeyboard.com/t/miryoku-and-homerow-mods/723/24?u=maexxx
2. avoid same-hand triggers: https://forum.ultimatehackingkeyboard.com/t/miryoku-and-homerow-mods/723/25?u=maexxx
