I'm trying to add some bindings to
undo-tree-visualizer-mode-map. To do so I use:
(define-key undo-tree-visualizer-mode-map (kbd "S-l") 'undo-tree-visualizer-quit)
But it doesn't work, and if I do
describe-keymap afterwards I see that the binding wasn't added.
There seems to be a few keymap where this behavior happens, such as
Info-mode-map as well.
Any idea why is that? And how can I add bindings to those keymaps?
