"""
Syntax for binding keys: bind(*keys, fnc)
keys are one or more key-combinations which are either:
* a string
* an integer which represents an ascii code
* a tuple of integers
fnc is a function which is called with the CommandArgument object.
The CommandArgument object has these methods:
cmdarg.fm: the file manager instance
cmdarg.wdg: the widget or ui instance
cmdarg.n: the number typed before the key combination (if allowed)
cmdarg.keys: the string representation of the used key combination
cmdarg.keybuffer: the keybuffer instance
Check ranger.keyapi for more information
