- Normally, when you trim 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.
- <dfn>Push/Pull trim</dfn>, 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:

- Here is what happens after we trim the right hand (selected) region by
- dragging its starting position earlier:

- 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.

<p>
- Lets look now at what happens if we do the same trim, but <kbd
- class="mouse mod3">Left</kbd>-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 <kbd class="mod3n"></kbd><kbd class="mouse">Left</kbd>-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.
