I don't think so. If I need to do a backward search in one of my long 3d programs I just go to my computer and do the search in my program editor ( I use the Predator editor bundled with Gibbs ) and go back to the controller. I assume you are aware that pressing the "T" key brings you to the top of the program, "B" brings you to the bottom, "BACKSPACE" & "ENTER" bring you back and forth one page at a time. On some of my long 3d programs however, I have found "T" & "B" only go so far and I have to press the keys again ?!?
