Set keymap for buffer, not major mode for that buffer

Set keymap for buffer, not major mode for that buffer

[Euler Herbert]

Hello,

Elisp manual says "If you change the current buffer's
local map, that usually affects all buffers using the
same major mode." [(info "(elisp)Changing Key Bindings")]

Is it possible to set keymap for a buffer, but only
affects the specific buffer using the same major mode?

Thanks in advance.

Regards,
Guanpeng Xu

Yes: create a new buffer specific keymap!

Yes.  Before doing a `local-set-key', do the following:

   (let ((origmap (current-local-map))
         (newmap (make-sparse-keymap)))
     (set-keymap-parent newmap origmap)
     (use-local-map newmap))
