# This configuration was completely stolen from Oh-My-ZSH:
# https://github.com/robbyrussell/oh-my-zsh/blob/master/lib/key-bindings.zsh
# Enchanced with more word actions (move backward and forward one word), I
# prefer ALT key to do same thing.

# Make sure that the terminal is in application mode when zle is active, since
# only then values from $terminfo are valid
