# ======================================================

# - Thanks to Kuglee on the Colemak forum for researching these bindings!
# - With my Extend mappings for instance, you can make the keyboard send XF86 multimedia keys
# - These are called XF86### where ### is for instance Cut/Copy/Paste (on Extend X/C/V)
# - Those key events are sent to the OS but not all of them do anything useful currently
# - The below script tells GTK to map the edit keys to actions so they work (in GTK apps at least)
