I am trying to bind C-c u and C-c r to winner-mode's undo and redo in my ~/.emacs:
(global-set-key (kbd "C-c u") 'winner-undo)
(global-set-key (kbd "C-c r") 'winner-redo)
However, this doesn't work without (winner-mode 1), which sets up some keybindings. And I don't want any of winner-mode's default keybindings. How can I make my winner-undo and winner-redo work without binding any other keys, preferably without installing other packages?
How about (setq winner-dont-bind-my-keys t)? The doc-string for that variable states "Non-nil means do not bind keys in Winner mode."
M-x find-library RET winner RET and i-searching for mode-map, which is a common naming convention for key-binding maps. In this case, it brought me to the winner-mode-map definition and I saw the variable winner-dont-bind-my-keys, and then I just went to the doc-string for that variable. If the library had been loaded beforehand, I could have typed M-x describe-variable or M-x find-variable to inspect the doc-string. If there was no such animal, then we could have unbound each key-binding that was undesired, or set the winner-mode-map to nil; or....
