Show Cue System

I have a question about remotely controlling Show Cue.

I'm a solo performer. I am building a new portable music control system. PC into a 4 or 6 channel mixer into a Bose L1, add a wireless mic, all in a waterproof pelican box.

My question: Is there a good remote control that I can start/stop the music on my PC. I was thinking a remote like a Powerpoint presenter remote. I'm looking for something that would be concealable in my pocket.

I used a mouse but with the left button disconnected, to avoid any mistake clicking in any unexpected place.
I disassembled the mouse and disconnected the switch of the left button.
Regards,
Lluís

Have a look at Options/Shortcuts. At the bottom of this page is a section entitled "Using a Wireless Presenter / Clicker with SCS". Does this help?
