shortcut for changing the view window

 From:  wimverbe

I thought this would be obvious to find a similar request or question in the threads, but didn't find.
is there a way to make a keyboard shortcut to change window views, e.g. from top view to 3D view? or a command to do this?
I am working with an Xkeys programmable keyboard and would like to put those under a key, like in other 3D programs.

thanks
