the evil f11

[Uwe Brauer]

Hi

I am completely puzzled by the following, for ages my emacs_keys.el file
contained the line

(global-set-key [(f11)]   'capitalize-word)

However since some time (I cannot remember when)

C-h k f11 gives
,----
| <f11> runs the command toggle-frame-fullscreen (found in global-map),
| which is an interactive compiled Lisp function in ‘frame.el’.
| 
| It is bound to <f11>.
`----

I usually have in my emacs init file the line
(load-library "emacs_keys.el")
or 
(require 'emacs_keys)

Even if I load it manually f11 is still bound to
toggle-frame-fullscreen.

Only when I enter the emacs_keys.el file
and eval
(global-set-key [(f11)]   'capitalize-word)

Then everything is fine.

I don't understand this because all the other binding is fine. It turns
me crazy.

Any help is strongly appreciated.
