Template Dialog

Template List: This is a list of all the available templates for the page. A name, description, and a thumbnail is given to help demonstrate what the template will look like. To select a template, simply click on one of the items in the list; the template will immediately be applied to the page.
Replace Actual Contents: If enabled (checked), this option will cause the entire page to be over-written with a default template layout. All of the content on the page will be lost with the switch to the new template, and will be filled with placeholder text. If disabled (unchecked), the current content on the page will be saved, but will most likely need to be further edited to integrate it with the new template choice.
