Mask opacity edit

[Centaurus]

Angelize, Alt-O works for me, thanks!

About applying the opacty mask to the objects: I wasn't very clear about that. I meant in version 6, I could select the masked object, make it "Convert to editable shapes" and got a cut object. Please see the attached picture.



Now I can only get to stage 2 (masked object). But I can't get to stage 3 (object cut with the mask object). Is it somehow possible?

PS: I tried to do that "Past opacity mask" thing but it didn't do any result at all for me.
Thanks!
