Tap Dance Layers

This feature creates a key that changes the current layer via tap dance. By default, this assumes that you have the following layers defined:

• _ADJUST
• _LOWER
• _RAISE
• _MOUSE

And sets up the following tap dance:

Count	Action	Layer
1x	hold	_ADJUST
1x	tap	_MOUSE
2x	tap	_LOWER
3x	tap	_RAISE
4x	tap	_ADJUST

Usage

NOTE: If you use other tap-dance functions, you may require additonal setup.

1. Copy features/dancelayers.{c,h} into your keymap or userspace directory.

2. Add the following to your rules.mk

   TAP_DANCE_ENABLE = yes
   
   SRC += ./features/dancelayers.c
   

3. Add the following to your keymap.c:

   #ifdef TAP_DANCE_ENABLE
   #    include "features/dancelayers.h"
   #    define TD_LAYR TD(TD_LAYERS)
   #else
   #    define TD_LAYR XXXXXXX
   #endif
   

4. Add TD_LYR to your keymap.

Functions and Enumerations

The following functions are available for use:

• cur_dance

The following tap dance enumerations are defined:

• TD_1X_HOLD
• TD_1X_TAP
• TD_2X_TAP
• TD_3X_TAP
• TD_4X_TAP

Overriding the Defaults

If you want to define different layers to tap dance actions, you'll need to define two additional functions in your keymap.c:

• td_lyr_finished
• td_lyr_reset

Both of these functions are necessary and require a certain pattern for each layer. "Tap" actions are handled in *_finished while "hold" actions are resolved in *_finished and *_reset.

See the implementation in dancelayers.c for an example.
