I am building some mods and I can't figure out what to search for to find what I'm looking for. What are the +- buttons called that I can use on the dna30 that push the onboard buttons? I literally am at a loss. Can't figure out what to search for. Anyone please help me here. I don't want to use the wired ones. I want to take advantage of what's already there so I can save space. Thank you for your help
