Changing the <dfn>length</dfn> of a region is a very common editing
|
|
operation, often known as <dfn>trimming</dfn>. There are several ways
|
|
to accomplish this with Ardour, and some very useful specialized trimming
|
|
operations.

<p>
|
|
In Grab mode, moving the pointer near the beginning or end of the region changes
|
|
the cursor to indicate that trimming is possible, and the edge of the region can
|
|
then be <kbd class="mouse">Left</kbd>-dragged in both directions.
|
|
</p>
|
|
<p>
|
|
Trimming will obey <a href="@@grid-controls">Snap settings</a>.

</p>

|
|
|
<h2>Other Trimming operations</h2>
|
|
<p>
|
|
There are several commands for region trimming. Some use the
|
|
<a href="@@edit-point-control">edit point</a> to determine where
|
|
to trim to. Some are not bound to any keys by default (but could be via the
|
|
<a href="@@default-keyboard-bindings">Keybindings Editor</a>).
|
|
</p>
|
|
<p>
|
|
These command are both in the <kbd class="menu">Region > Trim</kbd> main menu
|
|
(with a region selected) or in the contect menu of a region, <kbd class="menu">
|
|
<kbd class="mouse">right</kbd> click on a region > <em>Name_Of_The_Region</em>
|
|
> Trim</kbd>
|
