### 2.6 Swap-Hands Action
The swap-hands action allows support for one-handed keyboards without requiring a separate layer. Set `ONEHAND_ENABLE` in the Makefile and define a `hand_swap_config` entry in your keymap. Now whenever the `ACTION_SWAP_HANDS` command is executed the keyboard is mirrored. For instance, to type "Hello, World" on QWERTY you would type `^Ge^s^s^w^c W^wr^sd`

### 2.6.1 Configuration
The configuration table is a simple 2-dimensional array to map from column/row to new column/row. Example `hand_swap_config` for Planck:
```
@ -471,6 +472,16 @@ const keypos_t hand_swap_config[MATRIX_ROWS][MATRIX_COLS] = {
Note that the array indices are reversed same as the matrix and the values are of type `keypos_t` which is `{col, row}` and all values are zero-based. In the example above, `hand_swap_config[2][4]` (third row, fifth column) would return {7, 2} (third row, eighth column).
### 2.6.2 Advanced Swap Commands
- **`ACTION_SWAP_HANDS()`** Swaps hands when pressed, returns to normal when released (momentary).
- **`ACTION_SWAP_HANDS_TOGGLE()`** Toggles swap on and off with every keypress.
- **`ACTION_SWAP_HANDS_TAP_TOGGLE()`** Toggles with a tap; momentary when held.
- **`ACTION_SWAP_HANDS_TAP_KEY(key)`** Sends `key` with a tap; momentary swap when held.
- **`ACTION_SWAP_HANDS_ON_OFF()`** Alias for `ACTION_SWAP_HANDS()`
- **`ACTION_SWAP_HANDS_OFF_ON()`** Momentarily turns off swap.
- **`ACTION_SWAP_HANDS_ON()`** Turns on swapping and leaves it on.
- **`ACTION_SWAP_HANDS_OFF()`** Turn off swapping and leaves it off. Good for returning to a known state.
