Beschreibung

I am unsure if this is a bug or expected behaviour. I've managed to simulate the behaviour I wanted with PERMISSIVE_HOLD and fine-tuning TAPPING_TERM to my preference, but nevertheless this surprised me.

Replicating:

  • in config, RETRO_TAPPING activated and TAPPING_TERM set to something low (or zero)
  • layout with two mod tap keys, eg LCTL_T(KC_MINS) and LSFT_T(KC_TAB)
  • hold one mod tap key, eg. LCTL_T
  • tap the other key, eg LSFT_T

What I expected: ctrl+tab is sent.

What happens: nothing is sent on the first tap. From the second tap onwards, the expected behaviour happens. So for whatever reason the first tap is eaten up.
