key function to change

[Andreas Diener via Users list for the GNU Emacs text editor <help-gnu-emacs@gnu.org>]

   Dear Madam or Sir,

   first: I am from Germany and only stumbling through the english
   language, so please excuse this kind of literature ...

   Some (quite long) time ago one of you guys helped me out, and I hope I
   can get a hint from you again.

   I am on Linux (Debian 12), Emacs from the repository (28.2), and I am
   using a standard keyboard without num block, but a menu key on the
   right corner next to the Ctrl key. Since the Alt key on the left to the
   Space bar is the only Alt/Meta key it is quite "interesting" which
   grips I have to manage using the key bindings with M/Alt with the left
   hand.
   For the Ctrl key I use the hand which is not busy with letter keys,
   e.g. for C-x s I take the rigth Ctrl key and type the x and s with the
   left hand, and I think that would be nice for the M/Alt key, too.

   As default the menu key on the right produces the M-x prefix, but I
   don't need it that often, so I would like to reduce this to M only
   (e.g. for M-f, M-d, M-w, M > etc.).
   Searching the web about this there are some interesting solutions, but
   I didn't find a solution for my idea, additional there seem to be
   different ways for Emacs on different systems like Windows, MacOS and
   Linux. And because I am not into writing software and have no idea
   about lisp programming, I am a bit helpless here.

   An entry in my .emacs file, which I tryed, does not work:
   (global-set-key [menu] 'meta)

   Best regards,
   Andreas Diener
