backspace
BS
<character> (BS) {ASCII} code 8, Control-H. The {control
character} that should cause most output devices to move their
current output position back to the previous character so that
the next character output will replace (or overprint) it.
Inputting a backspace (typically by pressing the backspace
key) causes many systems to delete the character before the
input cursor, though others use {delete} for this.
See {twirling baton} for an imaginitive use of backspace.
