In readme file are described possible keybindings:
Keybindings you can set:
Toggle Original Map
Toggle Normal or Max Map
Toggle None or Max Map
Toggle None or Normal Map
Restore Saved Map Scale
Toggle Full Size Minimap
Toggle Favorites
Toggle Guide
Toggle Warehouse
Toggle Watch List Minimize
Anyway there is not mentioned how to set these keybindings.
Also cant find such a place in Carbonite options list.
Probably it is possible with manual modification of .lua files,
but this is beyond my abilities.
