That is really nice to have such a remote keyboard!
Recently, I attached a small (travelers) mouse to my SDS5104, and after initial hesitation, I now find myself using it more and more. Unfortunately, I have not figured out yet how to reach all features with the mouse, and have to reach out from time to time to the knobs!
Also, I made my instrument rack such, that I can slide it back and forth on my bench. I can move it closer when I need to operate any of the instruments.
Cheers,
rudi
