Keyboard short cut for back and front

[rajah]

I hope I did not miss it completely, but is
there a keyboard shortcut for back and front?
There is a Ctrl-P for going to previous locations
but is there one for going the other way?

I am using the button to do that right now and
its confusing with the back and front buttons
looking similar to the undo and redo buttons
sitting right next to each other.
A separator or reordering of buttons could
solve that problem.

Thanks,
Rajah
