Emacs: what is the shortcut key to clear buffer?
EmacsEmacs Problem Overview
Like, Control-A (select all) followed by delete?
Emacs Solutions
Solution 1 - Emacs
How about using:
M-x erase-buffer
Which you could bind to whatever you want.
Solution 2 - Emacs
C-x h + del key clears the buffer
Note: This requires transient-mark-mode to be enabled (which it is by default).
Solution 3 - Emacs
Select all in Emacs is:
C-x h
(technically, that's mark-whole-buffer) and kill-region (to kill the marked region, which is now the entire buffer) is:
C-w
If you want to delete the region without copying it to the kill-ring, you can use
M-x delete-region
instead. If you do this alot, you'll want to bind delete-region to a key/key combo.
Solution 4 - Emacs
These macros build on the answers given above. To start using them paste them into your .emacs then restart emacs or (while in the .emacs buffer) type M-x eval-buffer.
(defun clear-buffer ()
"clear whole buffer add contents to the kill ring"
(interactive)
(kill-region (point-min) (point-max))
)
(defun clear-buffer-permenantly ()
"clear whole buffer, contents is not added to the kill ring"
(interactive)
(delete-region (point-min) (point-max))
)
Solution 5 - Emacs
Old folks might like to call it hk rather than clear-buffer-permanently, and assign it to the nostalgic key sequence like so:
(define-key esc-map "\^[hk" 'hk)
That's the pre-Gnu TECO EMACS command to clear the buffer (ESC ESC wHole Kill).
Solution 6 - Emacs
Go to the begin of the buffer, go to the end (both set the mark), then cut:
M-< M-> C-w
Solution 7 - Emacs
There is no shortcut, but you can define one... Follow this link to get a macro for clearing a buffer.
