Is there an easy way to select everything in a box (including all cells as well as paint)? Basically I want to stretch something in an entire area to a different location, but this includes a lot of cells/paint. I know that "a" selects all layers, and I can manually add each cell to the selection with "I," but is there a faster way to do this?

First unexpand all subcells, then select everything, do the move or copy, and then expand again.

Yep, didn't think to unexpand first, thanks!

It's not an obvious solution, I'll admit.
