<title>Editing Concepts</title>
<para>
In Ardour, "editing" describes the process of
</para>
<itemizedlist>
<listitem>
<para>
making modifications to playlists. Recall that
<glossterm linkend="gt-playlist">playlists</glossterm> are nothing more
than lists of <glossterm linkend="gt-region">regions</glossterm> arranged
over time.

<title>Snap Settings</title>
<para>
By default, when you move objects around, they move freely. There
<emphasis>is</emphasis> a "granularity" to the motion, but it is a single
audio frame (so typically on the order of 1/48000'th or 1/96000'th of a
second), and at most zoom levels it will not be apparent in any way.
</para>
<para>
However, this is not always the way you want to move some kinds of objects.
If you are working with structured compositions that utilize traditional
concepts of bars, beats, rythmn and so forth, you will often want to move
regions so that that they always align to specific periodic time points
that correspond to the start of a bar, or a beat etc. If you are working on
a movie soundtrack, you may prefer to have regions always align to SMPTE
frames, or perhaps even to whole seconds.
</para>
<para>
Ardour provides a wide variety of "snap" settings. If any but "None" is
selected, they define a grid of timepoints which will be used to "snap"
object positions as they are dragged. The grid can be regular (as is the
case if you choose "Beats", for example), or it can be completely irregular
(if you choose "Marks", for example). It can even consist of a
<emphasis>single</emphasis> timepoint (if you choose "Edit cursor", for
example).

Move the mouse pointer to the toolbar panel of the editor window. Click on
the "expansion arrow" of the "Snap setting" chooser. This will popup a
list of available snap settings. If necessary, scroll down to see your
desired choice. Click on your choice in the list to dismiss it and make
Ardour switch to the new setting.
</para>
<note>
<para>
Changing snap settings has <emphasis>no</emphasis> effect on the position
of any existing region. Its effect is only on objects being moved.
</para>
</note>
<tip>
<para>
The snap setting also affects moving the playhead, the edit cursor,
loop/punch and location markers, and dragging/moving range selections.
</para>
</tip>

<section id="snap-mode">
<title> Snap Mode </title>
<para>
There are two subtly different ways in which the snap setting can affect
region motion:
</para>
<variablelist>
<title></title>
<varlistentry>
<term>normal snap mode</term>
<listitem>
<para>
regions can only be moved to positions defined by the snap setting. It
is not possible to move them to intermediate positions.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>magnetic snap mode</term>
<listitem>
<para>
regions can still be moved to positions not defined by the setting, but
they "stick" to the timepoints that are when dragged across them.
Imagine that the timepoints and the regions are magnetic - or just try
it and see.
</para>
</listitem>
</varlistentry>
</variablelist>
<para>
However, you can press the <emphasis>snap modifier</emphasis> key while
dragging, and the snap setting will be ignored. By default, this is the
key on your keyboard that generates <emphasis>Mod3</emphasis> , but you
can modify this from the <emphasis>Options Editor</emphasis> keyboard tab.
