I am still not sure what you are asking, but Art privately sent me a pre beta version of Mach. This version alows a slider to be assingend to the DRO. Meaning you do not need a keyboard to input digits. Its intention is not only asthetic, but will mean you could change the digits via a touch screen too. Is this what you wanted to do in your original post? If so, its release is imminant, excpt I did send him back to do a few modifications b4 he released it.
