# Combos
|
|
Combos allow you to assign special functionality to combinations of key presses.
|
|
The two default behaviors are:
|
|
* Chords: match keys in random order, all pressed within 50ms.
|
|
* Sequences: match keys in order, pressed within 1s of one another.
|
|
|
|
You can define combos to listen to any valid KMK key, even internal or
|
|
functional keys, like HoldTap. When using internal KMK keys, be aware that the
|
|
order of modules matters.
|
|
|
|
The result of a combo is another key being pressed/released; if the desired
|
|
action isn't covered by KMK keys: create your own with `make_key` and attach
|
|
corresponding handlers.
|
|
|
|
Combos may overlap, i.e. share match keys amongst each other.
|
|
|
|
The optional arguments `timeout` and `per_key_timeout` define the time window
|
|
within which the match has to happen and whether the timeout is renewed after
|
|
each key press, respectively. These can be customized for every combo
|
|
individually.
