About the scratch area
You can use the scratch area as a place to create or hold objects that you don't currently want on any page. The scratch area is the same for all pages in your publication. When you place an object in the scratch area while you are viewing one page, you can see it and access it when you view any other page in the publication. This makes the scratch area a useful holding place for objects that you don't want to delete but can't immediately use.
For example, if you have an object on one page (such as a text box or picture) that you want to use on another page, you can move it into the scratch area while you continue to work on the current page. Later, you can go to the page you want to move the object to and drag the object onto the page from the scratch area.
