<context> To modify an existing item in a Snippets drawer, complete the steps
listed below. If you have just completed the task <xref href="tsrcedt015.dita"
type="task">Adding an item to a snippets drawer</xref> and the <wintitle>Customize
Palette</wintitle> window is still open, you can skip steps 1 and 2.</context>
<steps>
<step><cmd>In the Snippets view, right-click the name of the item that you
want to modify, and select <uicontrol>Customize</uicontrol>.</cmd></step>
<step><cmd>Optionally, type a new name and a new description for the item.</cmd>
</step>
<step><cmd>To declare a variable, click <uicontrol>New</uicontrol> and type
the variable's name, description, and default value.</cmd></step>
<step><cmd>To edit an existing variable, type over the existing values.</cmd>
</step>
<step><cmd>To edit the <uicontrol>Template Pattern</uicontrol> field, type
into the field, cut and paste into the field, or, if you have defined one
or more variables, click the <uicontrol>Insert Variable Placeholder</uicontrol> button,
and double-click the name of the variable that you want to insert.</cmd><stepxmp>For
example, if you have declare variables named <varname>uri</varname> and <varname>prefix</varname>,
clicking the button brings up a menu that contains those names. Double-clicking <varname>uri</varname> inserts <codeph>${uri}</codeph>,
as in the following example:<codeblock>&lt;%@ taglib uri="${uri}" prefix="${prefix}" %></codeblock></stepxmp>
<stepresult>Later, when you insert the snippet into a file, <codeph>${uri}</codeph> and <codeph>${prefix}</codeph> are
each converted to the default value declared in the Variables table. Users
can replace the default values in the <uicontrol>Insert Template:</uicontrol><varname>Item_name</varname> dialog
at insertion time.</stepresult></step>
