Track Select Forward: select all the tracks
previous to the point clicked. (Selecting edits that are 5min, 1hr
long is tough).
Track Select Backward: select all the track after the point
and drag. Note that you are only moving one edge of the clip.
: can shorten or lengthen a clip by dragging on the In/Out edit points on the timeline. It will also ripple shift the rest of the sequence thereby changing the overall length.
: trims the Out point of one clip and the In point of the following clip simultaneously.
: adjusts both the In/Out points in a single clip at the same time.
: involves three clips. Shifts (slides) the middle clip left or right without changing its length.
: slice thru tracks and split them into separate clips.
