I haven't played with it that much, but I don't think you can.  I don't know
what programmable controls are available - I haven't read the instructions.

There seem to be 3 "windows" on the thing.  The top one appears to be the
"projection booth" then there's one about 1/3 up from the bottom, and
another just above the very bottom.  My guess is that the lower 2 have
sensors, probably CCD, and all need to focus, or intersect, on the typing
surface.  I wouldn't be too surprised if you couldn't type in "free space",
but then you wouldn't see the places to go to, to get the desired key.  Like
I say, I haven't played much with it.  I was out the day it came in, and I
got to get something else done first.

???? I noticed it didn't have all the Function keys.  Insetad it had some
funny "icon" like keys for the top row. I jst didn't think about the
three-fingered salute.
