Re: List of major modes? // "switch-to-mode"??

[David Reitter]

Thanks for your help with this.

Here is my fusion of your code, not using the documentation strings,  
but using apropos-internal to speed things up:

(apropos-internal
"-mode\\'"
(lambda (mode)
   (and (commandp mode)
        (not (string-match "\\`turn-\\(on\\|off\\)-"
                           (symbol-name mode)))
        (not (assq mode minor-mode-alist)))))


Here's why I wanted this:

I'd like to come up with a function switch-to-buffer that could be  
used interactively instead of M-x, with the advantage that completion  
would only complete mode names, and it would be able to display a  
list of modes (together with the first lines of their documentation  
strings) .

Has anyone already written something like this? (or is there an Emacs  
function that I don't know of...?)
