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, when trimming a region
|
|
that directly adjoins another, the desired result is to move the boundary
|
|
between the regions and not to make these regions overlap. This requires trimming both
|
|
regions on either side of the junction, in opposite directions.
|
|
<dfn>Push/Pull trim</dfn>, activated by pressing <kbd class="mod3n"></kbd> key before
|
|
starting the drag, will do just that.

The following pictures show the difference in the results of a normal trim and
|
|
a push/pull trim:

|
|
In the initial situation, before trimming, two adjacent regions are present,
|
|
the rightmost-one being selected.

|
|
<p>
|
|
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.

|
|
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.
