Emacs Lisp: switch-to-scratch and return back to previous buffer
This function is using register 100 to
switch-to-scratch and remembers where to return back. Global key binding is Hyper key and 8 and once in the
*scratch* buffer, the local key binding is to return back to previous buffer.
I could not make it without using registers. The local binding would not remember the buffer, but as registers are global so I am using it. I could as well use some global variable.
defun switch-to-scratch () ("Moves to scratch and remembers how to move back by using registers" (interactive)100 (current-buffer)) (set-register (persistent-scratch-restore)"*scratch*") (switch-to-buffer "s-8") (lambda () (interactive) (local-set-key (kbd 100))))) (switch-to-buffer (get-register "s-8") 'switch-to-scratch)(global-set-key (kbd
There are many ways to switch to buffer and return back.
*scratch* buffer with
emacs-lisp-mode is used on my side very often for calculations and estimates, new functions and similar. This function is using
persistent-scratch package and it would restore the
*scratch* if it does not exist. If you do not have the
persistent-scratch then simple remove the line above.
