Delete key
From Wikipedia, the free encyclopedia
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 ASCII value of the delete key is 0x7F (0177), 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 PCs used the backspace (0x08, or control-H) instead.
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 oftentimes the third key in from the right.
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).
On a Macintosh laptop to use the delete key the correct key sequence is Fn and the backspace key.
