It seems to be just by chance that I get it right when simply wanting to move a mask (all nodes selected). Have tried all kinds of Ctrl, Alt, etc. combos Even the right-click Select Menu/All, but the moment I touch the edge of the mask, it selects a segment, not the whole thing.
Had it figured out a while back, but brain is now blank.
Nothing in Vegas 6 Help files that I can find,. This is a most likely a stupid question but it's really frustrating, and I do feel stupid.
Time to hang it up and get some sleep.
Hopefully I'll wake up tomorrow in a brighter mood to find your your "duh" solution....
