To build your own customized Query, based on an existing Query , the Template mechanism in the General tab provides a convenient way to do this.
Click the Template pull-down menu in the General Tab. A list of available Query templates display.
Select the desired template, and then select the Load button.
Doing these two steps erases any existing Query definition in the Editor, and replaces it with a copy of the templates Editor (except for the new Query name you must enter). See Creating a New Attribute Query .
