Did you know F12 on the regular keyboard will also do it? Maybe you can turn on the On-Screen Keyboard and use the F12 there? That is if you have a workstation. Also, I would think that you could use a discrete input (button) and have it trigger in a seq block to do a silence horn silence command. Anyone else have ideas? Ronald G.
