since cellblock takes the focus of the keyboard from the "key" object, i can't detect needed keystrokes once something is selected in the cellblock! Is there a way to take the focus from cellblock without having to select something else?
yes, it's a hack, and exactly what I wanted to avoid, since a message such as "deselect" or "please give me my keyboard back. dammit!" is more elegant than getting into machinations of shiva and vishnu.
i decided on using the row selection data output to trigger a select to a number box. fortunately, i don't need my numberkeys, as those would get sucked up by the now-selected number box!!
