# If you bind the same key to multiple actions, the second and subsequent\n\
# bindings will be ignored--and you'll get a warning when the game starts.\n\
# Keys are case-sensitive, of course; c and C are different.\n\
 \n\
# WARNING: If you skip an action identifier, there will be no key bound to\n\
# that action!  You will be NOT be warned of this when the game starts.\n\

# That is, binding w to move_n will let you use w to move north, but you\n\

# For now, you must use vikeys, the numpad, or arrow keys for those actions.\n\
# This is planned to change in the future.\n\
