Tom Schmidt, one of our technicians here at FirstTech in Minneapolis wrote a script that brings up Apple's Mac OS X on-screen keyboard viewer for Mac OS X Lion and Mountain Lion. Apple has moved their keyboard around a few times with various updates over the years. This little script looks like an application and it can be put on your Mac OS X dock or you can add it to ActivInspire as a User-defined button. I have tested it and it seams to work well!
Hope you can find it useful.
Happy Holidays!
