blender 2.5

I did not find a way to change the buttons in the Properties (used to be Buttons). Lets say that I would like to make the F5 key pop up the materials, will that not be possible? I hope so, if not then it will not be totally customizable which everyone says.

Blender 2.5 is working in progress now. I think this fuction isn’t ready yet.

Ok, ye I know it is. But the hot key menu seems quite finished. Is there anywhere I can let them know that I would like this feature??
