<title>Snippets</title>
<p><app>Snippets</app> provide a convenient way of inserting repetitive
portions of code into your files. For example, an HTML snippet for the
<code><![CDATA[<img>]]></code> tag would insert the opening and closing
portions of the tag, as well as fixed places where you can enter image
attributes. This can make writing code easier and faster.</p>

<note style="important">
<p>Make sure the syntax is set appropriately. The status bar at the
bottom of the <app>gedit</app> window will show the current language
setting. This language setting is what allows gedit to insert the
proper snippets. <app>Gedit</app> will normally detect the language or
syntax of the file that you're using, but sometimes you may need to
set it.</p>

<title>Adding Snippets</title>
<p>You can add new Snippets that work either globally (that is, they are
language agnostic) or only in a particular syntax.</p>
<steps>
<item>
<p>Select <guiseq style="menu"><gui style="menuitem">Tools</gui>
<gui style="menuitem">Manage Snippets</gui></guiseq>.</p>
</item>
<item>
<p>From the <gui>Manage Snippets</gui> sidebar select the desired syntax
and click on the "+" button to list existing snippets for the selected
syntax.</p>
<note style="tip">
<p>To add a snippet that works globally (that is, when no particular
syntax or language has been set for the document), select
<gui>Global</gui> from the <gui>Manage Snippets</gui> sidebar.</p>
</note>
</item>
<item>
<p>To add a new snippet, click on the "plus" icon in the
<gui>Manage Snippets</gui> sidebar.</p>
</item>
<item>
<p>Input a name for the new snippet. The name of the snippet can be
different from the snippet you want to add.</p>
</item>
<item>
<p>Under the <gui style="group">Activation</gui> section, you must
input a term for the <gui style="input">Tab trigger:</gui> textarea.
You will be using this term to insert your snippet.</p>
<note style="tip">
<p>If you wish to insert a snippet with a keyboard shortcut, then
click your mouse pointer on <gui style="input">Shortcut key:</gui>
textarea and press the desired combination of keys. Once you have
pressed and released the keys, the keyboard shortcut will be set.</p>
</note>
</item>
<item>
<p>Under the textarea for <gui style="input">Edit:</gui>, input the

variables, where <em>n</em> is replaced with a number that
represents the numerical order of variables included.</p>

<title>New Snippet Example</title>
<p>Consider you have created a snippet with the term <var>greetings</var>
in <gui style="input">Tab trigger:</gui>. The
<gui style="input">Edit:</gui> textarea contains:</p>
<code>
<![CDATA[<greetings>Hello ${1:wonderful}${2:amazing} world!
</greetings>]]>
