Grids 1-3 were tested by my 11-year-old, who provided some invaluable feedback.
Observations:
1) it was fun to write, and it helped learn/reinforce some of the things I knew about IQ. (I really know my "enters" and my "ctrl-enters" now!)
2) the child pages in the manual were put in (quickly) for reference. I used my normal working IQ, rather than start up a stock version.
3) I'm a little burnt out (with tutorial writing, not IQ of course). Any revisions, feel free to update the zip file and upload it again; the system allows it. Else you can attach a renamed file.
