Registry tweak for remapping hardware buttons on xv6800

[iluv2Samba]

First time poster here. I must say this is a great forum with a wealth of very useful information. I'd like to remap the hardware buttons on the sides of the xv6800 such as the "ok" and "camera" buttons. I know you can reassign the buttons' functions by going to Settings -> Buttons. For example, "Button 5" has the additional option to assign a function to "Press and hold". How can I add this option to the other buttons? Is there a registry hack to achieve this? I'd rather find a way do this without installing AE Button Plus. Thanks for your help!
