A pattern flyer showed me the method that I still use. Using the neck strap and lay the transmitter down flat. Pinch both sticks between the thumbs and first fingers. Lay the next finger down across the transmiter in front of the first row of switches, and the next finger in between the first and second row of switches. Then lay the last fingers behind the second row of switches. That way once you get to know your transmitter, you will never have to look down at it to find the switch, and you can toggle it either way.
I've read that three times, and still can't picture what your transmitter looks like.
However, this discussion reminds me of all the ways people play a guitar. Fret with one hand, strum with thumb. Or a pick. Or finger pick. Or hammer on the neck with fingers from both hands. Thought I'd seen it all until I looked up Tommy Emmanuel on You Tube, playing Classical Gas. (Awesome!)
