Thanks to snapenilk for the variable blocks.
Use the arrow keys to move the variable watcher.
It's a real variable, not a sprite that looks like one. Look inside if you don't believe me.
(There's a Snap bug: if you edit the project, get out a "set variable watcher [normal/large/slider]" block and click on the dropdown menu, all of the options are on one line, which did not happen when I saved the project.)
