 ** Keybindings

 By default, all key bindings are prefixed with a value stored in
 =winum-keymap-prefix=, by default ~C-x w~. See [[Customize options][Customize options]].

+The default prefix is ~C-x w~ for compatibility with native Emacs bindings.
+However, it gives long key bindings and can be incomfortable to use.
+
+For instance, you can replace the native prefix with ~C-c~ or ~M-m~.
