I may have linked to the wrong Apple Keyboard. The one I have is about as long as my Ipad [10 to 11 inches]. But it's half as wide as the Ipad.
I don't use a stand. I either sit it on a table top, or use it on my lap/leg.
When I type, i don't pay attention to what is occurring on the screen, I just watch where my hand is on the keyboard. When I am finished typing I then check the screen.
At home, on this PC [The box sits 8 feet away from me, I'm on a wireless keyboard], I use a piece of wood with a couch cushion under it, as the keyboard stand. The wood was from a book shelf I threw away, the couch cushion is from our ratty 40 year old couch.
But when I am at the cancer clinic and am taking notes, I just use the table top that is in the examine room.
