Slightly OT but maybe relevant to OP or others.
I have a little external number pad that I keep beside me when I'm recording myself. It works better than a foot switch because I can assign a whole load of functions via "actions" like record/stop/keep (or delete) recorded files, create track, etc.
It's on a usb extension direct to laptop. Also - very cheap.
