I want to change a couple of key bindings for @wasamasa's eyebrowse package, because I'm on a laptop and the keys < and > aren't easy to access.

The thing is, this package defines a custom prefix for all bindings (C-c C-w). This confuses me because I don't know if a normal

(define-key eyebrowse-mode-keymap (kbd "z") 'eyebrowse-prev-window-config)

will do the job.

If I understand the question correctly, you should be able to change bindings in the eyebrowse-mode-map (note, not ...-keymap) and access them with the default C-c C-w prefix:

(define-key eyebrowse-mode-map "z" 'eyebrowse-prev-window-config)

Now, C-c C-w z and C-c C-w < (the original default) should both call eyebrowse-prev-window-config.

EDIT: I'm a bit surprised that the above code didn't work (just tested it myself), but the following does. Note that you could also do (kbd "C-c C-w z"), but the advantage of the concat version is that it will reflect whatever you customized choice of prefix keys is:

(define-key eyebrowse-mode-map
  (kbd (concat eyebrowse-keymap-prefix "z")) 'eyebrowse-prev-window-config)
  • C-c C-w z is undefined

    The working of the first version is dependent on how the keymap is defined. In general, it probably won't work.
