By default, M-s a prefix key bound to search-map, containing commands like occur (M-s o) and isearch-forward-word (M-s w).

I thought I'd change my search-map prefix key to ESC M-s in order to use M-s for save-buffer (I'm on a Mac and I use as my meta key).

I like the bind-key package, but I can't figure out how to bind a prefix key to a keymap with it. I naively tried:

(bind-keys ("M-s"     . save-buffer)
           ("ESC M-s" . search-map))

but that doesn't work because bind-keys expects an alist whose values are commands, but search-map is a keymap.

I've resorted to doing it without any of bind-key's helper functions:

(global-set-key (kbd "ESC M-s") search-map)

I see bind-key has the ability to bind keys within a particular map, and to define a new prefix map, but I don't see a way to bind to an existing map. Maybe there is no way to do this using bind-key macros, but I thought I'd ask in case anyone knows otherwise.

I'm not totally convinced I want to move the search-map onto a less convenient prefix key just to get saving bound to ⌘S, but I'd like to try it out.

Although bind-keys can't do this, bind-key can:

(bind-key "ESC M-s" search-map)
