On computer
keyboards, the delete key (sometimes shortened "Del"), should,
during normal text editing, discard the character at the cursor's
position, moving all following characters one position "back"
towards the freed place. On Macintosh computers, however, the
backspace key is
called the delete key, while a separate key, also called delete and
in the traditional location above the cursor arrows, serves as a
forward delete key.
The delete key may generate the ASCII delete
character, 7F hex (127 decimal), which reflects its history in
7-bit paper tape. If
a character was punched erroneously, punching out all seven bits
caused it to be ignored (or deleted). Unix retained the Delete key
as the way to erase characters, while DOS/Windows used the
backspace (0x08, or control-H) instead. The delete key may also be
mapped to ESC [3 ~ which is the VT220 escape code for
the "delete character" key.
On many notebook computer keyboards the key
labeled Delete (sometimes Delete and Backspace are printed on the
same key) serves the same purpose as a Backspace key. Othertimes,
the Delete Key is in its original IBM notebook position of above
and to the right of the Backspace key. Many laptops, to add keys on
a non-standard size keyboard add rows of smaller keys above the
Function Key line. On this line, the Delete Key is often the third
key in from the right. On Apple Inc.'s
line of laptops (notably the MacBook and
MacBook
Pro), the function of the delete key can be achieved by
pressing the Fn
key and the delete/backspace key.
Sometimes this desired effect is replaced by
inserting "^H" (or, less frequently, "^?") instead. This is related
to
ASCII control characters for BS and DEL.
Also, the delete key often works as a generic
command to remove an object (such as an image embedded in a
document, or a file in a file
manager).
