A black dot means it could potentially happen, and a clear dot means it definitely won't. I'm pretty sure that this is correct, but somebody might like to check it. I picked mode 8 because by default it works on the current wave, but doesn't allow execution relative to the cursor - a combination that's not explicitly available. And yes, some of these combinations are clearly silly.
And this is the only copy anywhere public of this information - despite the fact that it's not too difficult to work it out, and it's clearly quite useful, Adobe have never seen fit to reveal it.
