> 1. Joel saying "I didn't understand that question" and then moving on might have been succinct and practical, but it was just not a good reflection of him.
He's presenting in the style of You Suck at Photoshop, a series of Photoshop videos in the same style.
At the beginning he says something like "this is basic to intermediate, but for you this is going to be stupid hard", which is from the first (?) YSAP, "Distort, Warp, & Layer Effects" [1].
Reading your single comment (and watching the linked clip) was very much worth my time! I never before realized that you can address Excel cells via a symbolic name instead of row/column-wise. That is very cool and probably very basic. Now I'm going to watch the rest of Joel's video!
