Are there any touchscreen directional button add-in programs for TouchFLO3D?

[WBFAir]

Hello all

I have a GPS mapping program called Delrome that so far seems to be working well with my Verizon TouchPro2.

The only down side is that the program is designed to use the typical directional button keys of a non-touch screen type device to do the zooming in an out.

So far I can do this just fine with the arrow keys on the slider keyboard but its kind of a pain to try to do while driving to open up the slider, find the key, set to the zoom to I think I might want an then close all that back up again.

So I was wondering if there were any add-on programs that put some touch screen buttons on the screen that I could assign those keyboard buttons to that might allow me to do this without having to open the slider board.

Thanks
