# ModTap Keycodes
Enabling ModTap will give you access to the following keycodes and can simply be
added to the modules list.

```python
from kmk.modules.modtap import ModTap
modtap = ModTap()
# optional: set a custom tap timeout in ms
# modtap.tap_time = 300
keyboard.modules.append(modtap)
```

## Custom HoldTap Behavior
The full ModTap signature is as follows:
```python
KC.MT(KC.TAP, KC.HOLD, prefer_hold=True, tap_interrupted=False, tap_time=None, repeat=False)
```
* `prefer_hold`: decides which keycode the ModTap key resolves to when another
  key is pressed before the timeout finishes. When `True` the hold keycode is
  chosen, the tap keycode when `False`.
* `tap_interrupted`: decides if the timeout will interrupt at the first other
  key press/down, or after the first other key up/release. Set to `True` for
  interrupt on release.
* `tap_time`: length of the tap timeout in milliseconds.
* `repeat`: decides how to interpret repeated presses if they happen within
  `tap_time` after a release.
  When `True` the repeated press sends the previous keycode, no matter
  how long the key remains pressed the second time.
  This allows to hold the tap keycode, or repeatedly tap the hold keycode.
  When `False` repeated presses are independent.

Each of these parameters can be set for every ModTap key individually.
