Awhile back I read an article that described a research project that asked,
"What's the most efficient way to do regular typing using only a mouse?"
The answer used a scheme where that most recent few characters are used to
predict the next few.  The predictions are presented in a window, and the
user clicks on the one (or a part of one) that is correct.  That way,
the user can get as many as ten or fifteen characters typed per mouse click.

I know that sounds pretty bizarre.  You had to be there 8-)

Has anyone seen or heard of such a system for the NeXT, either product, demo,
or prototype?  I believe there is a commercial version for Mac.  Anyone
know its name?

thanks
