I'm new to Pedable. It recognizes my Infinity foot pedal. I used the Wizard to set up alt+J, which is the command for "play audio" in my software I want to use it with. I assume I want to click on "send key combination," but it's not working. What am I doing wrong? Also, the Infinity pedal has three segments, the middle usually being used for "play" and the right and left for fast forward and rewind. How do I set these up?
