# This is meant to be bound to key sequences such as \e#. It provides a simple way to quickly
# comment/uncomment the current command. This is something introduced by the Korn shell (ksh) in
# 1993. It allows you to capture a command in the shell history without executing it. Then
# retrieving the command from the shell history and removing the comment chars.
#
# This deliberately does not execute the command when removing the comment characters to give you an
# opportunity to modify the command.
