[mythtv-users] Back button in menus?

[Xamindar]

Is it possible to add a back button in the mythtv menus so instead of 
pressing esc or the left arrow button I can just press the back button 
on the myth screen to go to the previous menu?  I have added things to 
the xml files before but I'm not quite sure how to add a button that 
will send me to the previous menu.  Do I just have the button call the 
previous menu much like other buttons call the next menu?

Thanks for any help.
