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