I got it to work however it has a blue background I think its called dashboard. In a previous computer the dashboard popped up when I hit the middle mouse button but the small apps popped up in front of the desktop with everything else still visible. So when I was adding things on my computer I could see them as I type into the calculator. Is the way you are describing only for the calendar app? The dashboard works just fine but I want to see the background instead of the blue screen with the apps only.
I got it to work not by your description but my cousins help. I am not opening any apps to use the calculator it is totally on it own with nothing else open. I press the F15 for the shortcut.
