 This is a little bit hacky but is less code than using =define-key=, and will
 also shadow the old bindings.
 
-*NB:* the ~`~ key is convenient on qwerty keyboards, however if you are using a
-      different keyboard you should replace it with the key beside ~1~.
-      For instance, ~²~ on an azerty keyboard.
+*NB:* Both ~`~ and ~²~ are mapped to =winum-select-window-by-number= to handle
+      both =qwerty= and =azerty= keyboard layouts.
+      If you are using a different kind of layout, the recommended place to map
+      it is the key beside ~1~.
