Asus EEEPC 1005HA Home/End keys

I have a lovely 1005HA running #! at the minute and love it.

There are just one little thing that gets to me about it - the position of the Home and End Keys.

As it stands they are at Fn+[left arrow] and Fn+[right arrow] respectively.

On other PCs I use these keys alot and find them even more essential when working with a small screen and no mouse for scrolling.  It's painful having them locked behind the Fn key.

Does anyone know if there is a way that I could switch the functionality of these keys with the Pause/Break and PrtSc Keys?

Thanks

Brian
