# The format for each line is an action identifier, followed by several\n\
# keys.  Any action may have an unlimited number of keys bound to it.\n\
# 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\
# If you're going to mess with stuff, maybe you should back this file up?\n\

# Note that movement keybindings ONLY apply to movement (for now).\n\
# That is, binding w to move_n will let you use w to move north, but you\n\
# cannot use w to smash north, examine to the north, etc.\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\
\n\
# Finally, there is no support for special keys, like spacebar, Home, and\n\
# so on.  This is not a planned feature, but if it's important to you, please\n\
