See the Leader feature page for more details and examples.

See Configuration Overview for instructions on how to change these settings.

Kconfig

Definition file: zmk/app/Kconfig

Config Type Description Default
CONFIG_ZMK_LEADER_MAX_KEYS_PER_SEQUENCE int Maximum number of leader sequences that use the same key position 4
CONFIG_ZMK_LEADER_MAX_SEQUENCES_PER_KEY int Maximum number of keys to press to activate a leader sequence 5

CONFIG_ZMK_LEADER_MAX_KEYS_PER_SEQUENCE sets the maximum length of a leader sequence.

If CONFIG_ZMK_LEADER_MAX_SEQUENCES_PER_KEY is 5, you can have 5 separate leader sequences that start with position 0, 5 leader sequences that start with position 1, and so on.

Devicetree

Applies to: compatible = "zmk,leader-sequences"

Definition file: zmk/app/dts/bindings/zmk,leader-sequences.yaml

The zmk,leader-sequences node itself has no properties. It should have one child node per leader sequence.

Each child node can have the following properties:

Property Type Description Default
bindings phandle-array A behavior to run when the leader sequence is triggered
key-positions array A list of key position indices for the keys which should trigger the leader sequence
immediate-trigger bool Triggers the leader sequence when all keys are pressed instead of waiting for the timeout (only applicable when one leader sequence overlaps another) false
layers array A list of layers on which the leader sequence may be triggered. -1 allows all layers. <-1>

The key-positions array must not be longer than the CONFIG_ZMK_LEADER_MAX_KEYS_PER_SEQUENCE setting, which defaults to 4. If you want a leader sequence that triggers when pressing 5 keys, then you must change the setting to 5.
