respond to key or mouse click other than just ESC?

Since the computrainer head unit can’t be used to stop the simulation I bought a tiny wireless keyboard/tracked unit hoping I.could use start or stop the simulation, however it cannot emit the ESC key. Could there be another key or mouse action that provides a way to pause and get to the save/exit screen?

Hmm, interestingly today when I stopped riding and coasted to a stop, I got a pop up that allowed me to exit. On all my previous rides I’d dismounted, walked over to the computer, and had to hit ESC. Given the automatic pop up this is no longer an issue for me.
