windows key as super

windows key as super

[Giovanni Gigante]

I am using emacs 22.2.1 on debian 5.0.3, through a VNC connection from a 
windows machine, and I am trying to configure the windows key for some 
emacs shortcut.
VNC is configured to "pass special keys directly to server".

Then I tried in emacs:
(global-set-key (kbd "s-s") 'save-buffer)

However, this does not seem to work. If I type "windows - s", all I get 
is an s.

According to xev, this is what happens when I tap the windows key in a 
terminal window:

KeyRelease event, serial 30, synthetic NO, window 0x2800001,
     root 0x2e, subw 0x0, time 118816809, (423,786), root:(448,849),
     state 0x0, keycode 255 (keysym 0xffeb, Super_L), same_screen YES,
     XLookupString gives 0 bytes:
     XFilterEvent returns: False

so it seems that the super key is being received after all, but emacs 
ignores it.

BTW, running emacs on the console (locally, sans VNC) gives the same result.
What am I doing wrong?

Thanks
Giovanni

Hm works for me (without VNC)

Keybindings are a science of it's own, I remember there was a huge
tutorial with dozens of pages about it somewhere in the internet, but
I can't find it anymore.

anyhow there is a trick I use, if just getting it done is more
important than  portability.

Try to bind interactively and investigate the generated lispcode with
"redo"

M-x local-set-key RET s-s RET save-buffer

C-x ESC ESC

What I get is: (local-set-key (quote [8388723]) (quote save-buffer))
which I can include (simplified) as

(local-set-key '[8388723] 'save-buffer)

in my .emacs.

You can also put point right after the large number and hit C-x C-e
twice: the echo area will then show you various alternative ways to
write this number:

  8388723 (#o40000163, #x800073, ?\s-s)

so you can then write:

  (local-set-key '[?\s-s] 'save-buffer)

Just curious: why quote the vector?

Duh, yes, sorry, I copy&pasted without even noticing it.

Thanks for all your replies and resources; however, I still have problems.
It seems that my windows key is mostly ignored by emacs. For example, if 
  I try "M-x local-set-key RET", and then I type windows-s, all emacs 
gets is the s; the windows key is not seen.
I've tried this in several settings, this is the result:

                                        gets windows keys?
(1) emacs -nw in linux cli console:    NO
(2) emacs -nw in gnome terminal:       NO
(3) emacs -nw remotely via ssh PuTTY:  NO
(4) X11 emacs locally:                 YES
(5) X11 emacs remotely via VNC:        NO

basically, only in one situation emacs notes that I pressed the windows key.
I can survive if it doesn't work in the text-only modes. However, what I 
am really interested is (5).
In both (4) and (5), xev reports "Super_L" being pressed, although with 
a different keycode (115 in (4), 255 in (5)). So it seems that the key 
press reaches X11 in both cases. Only, in (5) emacs ignores it. Any idea 
why?

Check with 'xmodmap -pm' your X11 modifier settings and then adjust  
accordingly!
