Happy clacking (wirelessly).
Good news: ZMK supports it—and it’s a game-changer for reducing finger contortions. zmk leader key
keymap { ... }; };
CONFIG_ZMK_LEADER=y Pro tip: If you are using Nice!Nano or other low-power controllers, enabling this adds minimal overhead. Your battery life will be fine. Now, open your keymap file ( .keymap ). You need to include the leader header and define what sequences do. #include <dt-bindings/zmk/leader
The actual mapping is usually done in your keymap layer using the &leader behavior. Here is the correct modern way to map specific sequences: Good news: ZMK supports it—and it’s a game-changer
