I guess it'd help if we knew what it does?
Avid systems also vary a lot, some are online and some offline from the little I know and a lot of what's designed for online editing isn't that applicable to offline editing unless you're trying to cross over.
Bob.
"Match Frame" does lenthen an event to the current cursor position if the cursor is outside of the selected event. I don't know of a shortcut for Vegas but it is nothing else then placing the timeline cursor first and then dragging the event's edge to the cursor position.
i think he's referring to match framing either between non consecutive takes, or two tapes (or more, as in the case of music clip).
in the first case i simple sync all takes on seperate tracks then decide between them (eg. drama scene), in the latter, put each take on it's own track, sync, 'em and simply cut between them.
Typically (if not exclusively) AVID match frame is used to match a frame in the timeline to the the same frame in a source file.
To do this in Vegas, select a timeline event, put the cursor anywhere inside the event, right click, open in trimmer. Trimmer is zoomed in to the timeline event boundaries, cursor matches timeline cursor.
