I know about the relabel function in the right-click menu when you right-click on a block, but I can't seem to find any info on it anywhere, even in the reference manual. (also, what category does this go in?)
Probably Help With Snap!
It changes a block into another one. For example, if you have ((5) * (3)) and you want to change it to ((5) + (3)), you just right click on the * block, click "relabel" and click the + block.
Page 109 for primitive relabel, 110 for custom block relabel. You scared me by saying that, but sure enough there's an index entry for relabel, pointing at both those pages.
ok, I didn't see it. Thanks.
