prompt_arrows_help() {
    cat << EOF
prompt arrows <right|2line> <normal> <prompt> <ssh> <urgent> <comment> <dir> <unwritable>

The first parameter determines whether or not to use right-aligned status
text, or to put it above the command line.

All other parameters are Zsh PROMPT_SUBST color values wrapped in '%F{}'.

If 'prompt' or 'ssh' are 'random', their respective value will be
procedurally generated using the machine hostname as a seed; if the
machine is connected to SSH, the 'prompt' value will be replaced with
the 'ssh' value.


Defaults are white, green, random, red, blue, yellow, and darkyellow
respectively.
