Re: New keybinding suggestion: C-x _ for `shrink-window'

[Richard Stallman]

    Actually, I'd prefer to deprecate those bindings (along with C-x ^) and
    replace them with a binding that allows the user to do:

       M-x window-resize RET

    (which we'd of course bind to some key) and then

       ^ ^ ^ } } } } } { { { { } } ...
    or
       left left left up up up up up up up

I think that is worth trying.  To make it convenient we need
a key binding for window-resize.  How about C-x _?
