My usual stuff

# Make auto-complete cycle through options instead of listing them all
TAB: menu-complete
# Make shift tab reverse the above
"\e[Z": "\e-1\C-i"
# Use up and down arrow to search command history. Invaluable!
"\e[A": history-search-backward
"\e[B": history-search-forward
# Use Control-g to keep a command in history without executing
"\C-g": "\C-a history -s \C-j"
