Sticky Layer Behavior

Summary​

A sticky layer stays pressed until another key is pressed. By using a sticky layer, you don't have to hold the layer key to access a layer. Instead, tap the sticky layer key to activate the layer until the next keypress.

By default, sticky layers stay pressed for a second if you don't press any other key. You can configure this with the release-after-ms setting (see below).

Behavior Binding​

  • Reference: &sl
  • Parameter #1: The layer to activate , e.g. 1

Example:

&sl 1

Configuration​

You can configure a different release-after-ms in your keymap:

&sl {
    release-after-ms = <2000>;
};

/ {
    keymap {
        ...
    };
};

Advanced usage​

Sticky layers behave slightly different from sticky keys. They are configured to quick-release. This means that the layer is released immediately when another key is pressed. "Normal" sticky keys are not quick-release; they are released when the next key is released. This makes it possible to combine sticky layers and sticky keys as such: tap &sl 1, tap &sk LSHIFT on layer 1, tap &kp A on base layer to output shift+A.

Comparison to QMK​

In QMK, sticky layers are known as 'one shot layers'.
