+ Normally, when trimming regions by dragging with the mouse, it affects
only the selected regions. Their lengths are directly affected by the
- trim operation, but nothing else is. Sometimes though, you might like
- to trim a region that directly adjoins another, and keep this relationship
- the same—you are not trying to make one of the regions extend
- over the other—you would like the junction to move in one
- direction or the other as part of the trim. This requires trimming both

regions on either side of the junction, in opposite directions.
- Push/Pull trim, activated by pressing shift key before
- starting the drag, will do just that. Here's a few pictures to show the
- difference in the results of a normal trim and push/pull trim. First,
- the initial situation:
+ Push/Pull trim, activated by pressing key before

- Here is what happens after we trim the right hand (selected) region by
- dragging its starting position earlier:
-
+ The following pictures show the difference in the results of a normal trim and
+ a push/pull trim:
+
- You can see that it now overlaps the earlier region and a crossfade has - been created between them. + In the initial situation, before trimming, two adjascent regions are present, + the rightmost-one being selected.
- Lets look now at what happens if we do the same trim, but Left-dragging to turn it into a push-pull trim instead: + The simple trim, obtained by dragging the selected region's starting position earlier, overlaps + the earlier region. A crossfade has been manually created between them, so their + sound will fade from the leftmost region to the rightmost one.
-- There is no overlap, and the end of the earlier region has been moved - along with the start of the later region, so that they still directly - adjoin each other. + If the same trim is done, but by Left-dragging + to turn it into a push-pull trim instead, there is no overlap, and the end of + the earlier region has been moved along with the start of the later region, so + that they still directly adjoin each other. In effect, it is like doing a simple + trim to reduce the leftmost region, then doing a simple trim to extend the rightmost + one to fill the gap.
