The menu item Help->List Effect Commands should open a dialog box, with a quick and easy reference instead of going outside to the internet.
For the very least, it should open a local HTML file (quick and compact, without all the tutorial and navigation stuff).
Just a small thing to add to this wonder-of-nature software.
It’s a pretty good suggestion but in the meantime I recommend printing a copy of the commands. It is only 4 pages and it’s very handy to have at hand when needed.
