Some F function key dont do what the picture say!

Dear all,

I had my keyboard, a German one, replaced by another German one, on my macbook, but its different to my old one because the speaker keys were F9-F11 or something like that.

Anyways, my issue is that my F7 has an All Windows function icon on it, but its the F9 key that actually does show all windows. How do I change/transfer the function from the F9 key to F7?

Also, how can I have a "free" F key used to refresh, because on the last keyboard, F5 was refresh and here it is part of the volume buttons!

Hope someone can help!

System Preferences - Keyboard - Keyboard Shortcuts

been there and tried it, but not sure how to do what I posted, sorry...

One example:

System Pref - Keyboard - Keyboard Shortcuts - Expose and Spaces on the left - double click on the F9 (to open a box there), not just on the line it's on, but on the F9 itself, at the right side of All Windows, press the F7 key - voila, changed

Now you'll probably have to go thru and hunt down the other item that was set to F7 already and change it.
Not really sure if changes made auto remove any shortcut that was already assigned to that key or not - am guessing it does, but I have not done this to test it out.

thank you, will try this!
