-<p>
- 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.
