- 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:
