Re: UAAG2 Guideline 4.1 Level A Only (following 3 April 2008 Call)

There are two ways that were propposed and they were both rejected as far as 
I know lausing the keyboard to controll the drawing tool and:
2> using characters as paints.  you type a character and then you move it 
around or you use the keyboard to pick from a pallet.  In any case, there 
are lots of way to do it.  The problem we run into is realtime.  if realtime 
motion is required, we cannot trap that with the keyboard but drawing we can 
do.
st I heard.

Hi Dave,

I'm not very comfortable with exceptions either...and didn't take it
lightly writing it...

How would you want to handle drawing, etc.? Driving the mouse with keys
or do you have something else in mind?

Cheers,
Jan
