The host you communicate with using MacTerminal may or may not support the
methods of backspacing available to you on the Macintosh. To determine whether
the host does recognize methods of backspacing used by the Macintosh, try
typing CTRL-H to delete a character, or hit the backspace key (upper right
corner of the keyboard) to reposition the cursor without deleting the
character. If neither method works, you'll need to consult the host's operating
manual.
NOTE: In version 2.0, the backspace and delete keys can be swapped.
