then how do they press "ok" or "cancel" or just about anything in x without
being able to "click" you need to heuristically think they'd want to click if
they rest on a position for a while. most things in x wont work without a click
(or a keystroke)

not sure how this makes it hard. you can still do all you need to. maybe you
just aren't using enough of x? :) you could do what you wanted via xtest and
pointer polling as well as the cursor controlled by the accessibility device
(taking your example) :)

just suggesting that i think you can do what you want... with or without grabs
:)
