# left/right direction follows the order in which directories
# were visited, like left/right arrows do in a browser

#  pushd +N: start counting from left of `dirs' output
#  pushd -N: start counting from right of `dirs' output

# These sequences work for xterm, Apple Terminal.app, and probably others.
# Not for rxvt-unicode, but it doesn't seem differentiate Ctrl-Shift-Arrow
# from plain Shift-Arrow, at least by default.
# iTerm2 does not have these key combinations defined by default; you will need
# to add them under "Keys" in your profile if you want to use this. You can do
# this conveniently by loading the "xterm with Numeric Keypad" preset.
