Oh........that on stage software looks the business due to the "remote control" section

Although how in the wild, wild west would you get a foot controller hooked up to a laptop?
I am new to this backing track talk as I always played in a live band previously so any "baby step" hints and what type of foot controller etc.., I would need would be great.
As I am the keyboard player I have got lumped with controlling the backing tracks however the remote feature above sounds great because ideally I would prefer if the lead singer controlled them "play/stop".
Thanks for any advice as ever
