The <DEL> (
delete-backward-char) command removes
the character before point, moving the cursor and the characters after
it backwards. If point was at the beginning of a line, this deletes
the preceding newline, joining this line to the previous one.
If, however, the region is active, <DEL> instead deletes the text in the region. See Mark, for a description of the region.
On most keyboards, <DEL> is labeled <BACKSPACE>, but we refer to it as <DEL> in this manual. (Do not confuse <DEL> with the <Delete> key; we will discuss <Delete> momentarily.) On some text terminals, Emacs may not recognize the <DEL> key properly. See DEL Does Not Delete, if you encounter this problem.
The <Delete> (
delete-forward-char) command deletes in the
“opposite direction”: it deletes the character after point, i.e., the
character under the cursor. If point was at the end of a line, this
joins the following line onto this one. Like <DEL>, it
deletes the text in the region if the region is active (see Mark).
delete-char) deletes the character after point,
similar to <Delete>, but regardless of whether the region is
See Deletion, for more detailed information about the above deletion commands.
kill-line) erases (kills) a line at a time. If
you type C-k at the beginning or middle of a line, it kills all
the text up to the end of the line. If you type C-k at the end
of a line, it joins that line with the following line.
See Killing, for more information about C-k and related commands.
