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.
