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>,
+ <a href="@@trimming-regions#trimtonextprevious">Trim to Next or Trim to Previous</a>,
depending on which end is covered.
