global-bind a function key

global-bind a function key

[Glen Stark]

Hi.  

I feel like this should be really simple but I'm having a hard time 
anyway.

I'm using emacs 24.2.1

Following the instructions here: http://www.delorie.com/gnu/docs/emacs/
emacs_497.html

I have the following line in my .emacs file:

	(global-set-key [f5] 'convert-include-type)

(convert-include-type is a function of my own definition).  

If I evaluate the above lisp expression I get no errors, but pressing the 
F5 key produces the message "<SunOpen> is undefined", which is apparently 
the default keybinding for F5.  

If I run "global-set-key, f5, convert-include-type" from the minibuffer, 
everything works as expected.  

I tried a couple other syntaxes for keybinding an f5 key that I found on 
the web, but so far I have had no luck.  Can someone help me out?  

Thanks,

Glen

It seems that your desktop environment (the equivalent to
KDE/Gnome/whatever you are using) translates F5 to the virtual key
<SunOpen>, which is what Emacs sees. This means that Emacs never sees
the F5 key as pressed, so it is no surprise that your global-set-key
doesn't work.

Here, when you interactively press F5, <SunOpen> is sent to Emacs, which
in practice means that you are binding <SunOpen>.

If I'm correct there is no syntax for F5 that works for your setup
because the desktop environment is translating the F5 press event to
<SunOpen>.

Maybe your desktop environment allows to remove the F5 -> <SunOpen>
mapping with some configuration tool.

Try 
        M-x command-history RET 

right after 

        M-x global-set-key RET 

or 
        M-x local-set-key RET

It is possible that the mystery be revealed to you.

Try 
        M-x list-command-history RET 

right after 

        M-x global-set-key RET 

or 
        M-x local-set-key RET

It is possible that the mystery be revealed to you.

First, thanks for everyone who took the time to reply.  I read them.

Second, I apologize for wasting your time.  I had the Flock key on my 
keyboard disabled, which I didn't discover until I tried to use f3 to 
define a macro.  

I feel quite silly now, it's unbelievable how much time I wasted on that.

Others have explained the problem: Emacs does not see <f5> when you press that
key.  It sees <SunOpen>.

Does this help?

(global-set-key (kbd "<SunOpen>") 'convert-include-type)

No, what it means is that your F5 key does not generate an `f5' event
but a `SunOpen' event instead.
Maybe you want

   (define-key function-key-map [SunOpen] [f5])
