Sends `register_code(<kc>)` and then `unregister_code(<kc>)`. This is useful if you want to send both the press and release events ("tap" the key, rather than hold it).
If you're having issues with taps (un)registering, you can add a delay between the register and unregister events by setting `#define TAP_CODE_DELAY 100` in your `config.h` file. The value is in milliseconds.
If `TAP_CODE_DELAY` is defined (default 0), this function waits that many milliseconds before calling `unregister_code(<kc>)`. This can be useful when you are having issues with taps (un)registering.
If the keycode is `KC_CAPS`, it waits `TAP_HOLD_CAPS_DELAY` milliseconds instead (default 80), as macOS prevents accidental Caps Lock activation by waiting for the key to be held for a certain amount of time.
### `tap_code_delay(<kc>, <delay>);`
Like `tap_code(<kc>)`, but with a `delay` parameter for specifying arbitrary intervals before sending the unregister event.
### `register_code16(<kc>);`, `unregister_code16(<kc>);` and `tap_code16(<kc>);`
