Hold-tap is the basis for other behaviors such as layer-tap and mod-tap.
Simply put, the hold-tap key will output the 'hold' behavior if it's held for a while, and output the 'tap' behavior when it's tapped quickly.
tapping_term_ms parameter decides between a 'tap' and a 'hold'.
By default, the hold-tap is configured to also select the 'hold' functionality if another key is tapped while it's active:
We call this the 'hold-preferred' flavor of hold-taps. While this flavor may work very well for a ctrl/escape key, it's not very well suited for home-row mods or layer-taps. That's why there are two more flavors to choose from: 'tap-preferred' and 'balanced'.
- The 'hold-preferred' flavor triggers the hold behavior when the tapping_term_ms has expired or another key is pressed.
- The 'balanced' flavor will trigger the hold behavior when the tapping_term_ms has expired or another key is pressed and released.
- The 'tap-preferred' flavor triggers the hold behavior when the tapping_term_ms has expired. It triggers the tap behavior when another key is pressed.
When the hold-tap key is released and the hold behavior has not been triggered, the tap behavior will trigger.
This example configures a hold-tap that works well for homerow mods:
If this config does not work for you, try the flavor "balanced" with a medium tapping_term_ms such as 200ms.
Comparison to QMK
The hold-preferred flavor works similar to the
HOLD_ON_OTHER_KEY_PRESS setting in QMK. The 'balanced' flavor is similar to the
PERMISSIVE_HOLD setting, and the
tap-preferred flavor is similar to
