You may have a situation where you have positioned one region over another,
|
|
and you just want to cut the lower region so that it directly adjoins both
|
|
ends of the overlapping one, with no overlaps. To do this, select the upper
|
|
region, then choose <kbd class="menu">Edit > Separate > Separate
|
|
Under</kbd>. This will split the lower region so that it no longer overlaps
|
|
the upper region at all. <br />
|
|
Here is an example where we start with a short region placed so that it
|
|
overlaps a longer region:
|
|
</p>
|
|
<img src="/images/a3_before_separate_under.png" alt="region arrangement before separate under" />
|
|
<p>
|
|
When we perform the <dfn>Separate Under</dfn> edit, the lower region splits
|
|
in two, with boundaries exactly positioned at the edges of the upper region:
|
|
</p>
|
|
<img src="/images/a3_after_separate_under.png" alt="region arrangement after separate under" />
|
|
<p>
|
|
If the upper region covers only one end of the lower region, then this
|
|
operation is equivalent to
|
|
<a href="/editing-and-arranging/change-region-lengths/#trimtonextprevious">Trim to Next or Trim to Previous</a>,
|
|
depending on which end is covered.
