Print key

Print key

[John Robot]

Hi,

How is it possible to map the "Print Screen" key of a keyboard
(under Emacs 21.3, on Win XP) to the print function?

I've tried "everything", but with no success...

    (global-set-key [(print)] 'ps-print-buffer-with-faces)

Help is welcome!

Best regards,
  John

`C-h v' followed by the Print Screen key on GNU Emacs 21.3.1
(i386-pc-solaris2.7, X toolkit) says "<print> is undefined".  So you
should use (kbd "<print>") instead of [(print)].

(global-set-key (kbd "<print>") 'ps-print-buffer-with-faces)

does not work either...

And `C-h k' does not print anything in the mini-buffer, as if
hitting the key did not function (it does function, though, in
all the other applications I'm using).

What does C-h k say?

On windows, that key seems to be called "snapshot" rather than "print".

Nothing. `describe-key' does not "see" the `Print Screen' key;
it does not display anything, still waiting for an input key...

Nope. Does not help ;-(

No. Still the same problem: hitting the `Print Screen' key does
not generate any activity...

Thanks for the try, still.

Best regards,

"Print Screen" is globally used by Windows as a hotkey (it puts a
screen snapshot on the clipboard). To override this, you need to get
Emacs to re-register it:

(w32-register-hot-key [snapshot])

Yeah!  The following code is now *perfectly* working:

(w32-register-hot-key [snapshot])
(global-set-key [(snapshot)] 'ps-print-buffer-with-faces)

Many thanks for your help!

Best regards,

It seems that something is eating the key before Emacs sees it.  To
check for sure, hit x then PrintScreen, then y.  Then C-h l.  Is
there something between x and y?

Good idea... Yes, there is `<snapshot>' between `x' and `y'.

But, anyway, my problem is now resolved* thanks to Jason Rumney
and the command:

    (w32-register-hot-key [snapshot])

before my key binding:

    (global-set-key [(snapshot)] 'ps-print-buffer-with-faces)

Best regards,
  John

* except in XEmacs where the function `w32-register-hot-key'
  does not work
