Hello, Marty:
Yes, I first said "show desktop", then "tab". If I repeatedly said "tab", Speech Recognition would take me to the desktop, then the taskbar, then a message would appear that says "show hidden icons" on the bottom right corner and right above the sound volume and battery icon (which doesn't do anything), then the button that has 2 options - "show desktop" & "peek at desktop"; in other words, it would run a "circle", if I kept on saying "tab".
Thank you!
