# Be more intelligent when autocompleting by also looking at the text after

# ~/src/mozillail", but to "cd ~/src/mozilla". (This is supported by the
# Readline used by Bash 4.)

#key mappings available
#  the 2 unused keystrokes with ctrl are the rather awkward:

#  Ctrl+^

#  but there are 15 letters available for  use with meta, namely:

#  Meta+J, Meta+K, Meta+M, Meta+O, Meta+Q,
#  Meta+S, Meta+V, Meta+W, Meta+X, and Meta
