 You can change a keymap by editing code of keymap.c like following.
 This is a keymap for AEK, however, also used for other keyboards.
-How to define the keymap is probably obvious. You can find key symbols in usb_keycodes.h.

 If you want to define some keymaps than just one, see hhkb/keymap.c and
