If the user attempts to activate layer 1 AND layer 2 at the same time (for example, by hitting their respective layer keys), layer 3 will be activated. Layers 1 and 2 will _also_ be activated, for the purposes of fallbacks (so a given key will fall back from 3 to 2, to 1 -- and only then to 0). +#### Naming your macros + +If you have a bunch of macros you want to refer to from your keymap, while keeping the keymap easily readable, you can just name them like so: + +``` +#define AUD_OFF M(6) +#define AUD_ON M(7) +#define MUS_OFF M(8) +#define MUS_ON M(9) +#define VC_IN M(10) +#define VC_DE M(11) +#define PLOVER M(12) +#define EXT_PLV M(13) +``` + +As was done on the [Planck default keymap](/keyboard/planck/keymaps/default/keymap.c#L33-L40) + #### Timer functionality It's possible to start timers and read values for time-specific events - here's an example: @@ -227,11 +244,91 @@ if (timer_elapsed(key_timer) < 100) { It's best to declare the `static uint16_t key_timer;` outside of the macro block (top of file, etc). +#### Example 1: Single-key copy/paste (hold to copy, tap to paste) + +With QMK, it's easy to make one key do two things, as long as one of those things is being a modifier. :) So if you want a key to act as Ctrl when held and send the letter R when tapped, that's easy: `CTL_T(KC_R)`.
