Intro

Momentary Layers (MOL) are layers that activate when a key is held and deactivate when released, similar to how the Shift key works.

This terminology comes from the keyboard modding community. For more details, see: https://zmk.dev/docs/keymaps/behaviors/layers#momentary-layer.

Terminal Support​

MOL requires terminals that support the Kitty Keyboard Protocol (KKP):

  • Alacritty
  • Ghostty
  • Foot
  • iTerm2
  • Rio
  • WezTerm
  • TuiOS terminal

Fallback​

If your terminal doesn't support KKP, Ki will still function, but you'll need to manually press esc to deactivate layers instead of simply releasing the key.
