I do not like the standard keybinding to redo so I would like to customise it. How can I remap redo to C-S-/? I am not able to find any solution in internet.
If you haven't already try undo-tree.el. It gives Emacs a conventional undo, otherwise you need to undo the undos in order to redo--there is no redo function... With it you can add:
(global-set-key (kbd "C-s-/") 'undo-tree-redo)
to your emacs init file, or where ever you keep custom keybindings, and walk back and forward through any change.
By default, Emacs doesn't support redo with a single key-stroke.
You can do one of the following.
- Write some elisp to perform both actions for you.
- This functionality has been made into a package called undo-fu.
- Use undo-tree or redo+, however both have long-standing bugs, so I wouldn't recommend this, see:
