Application window

The bar to the left of the document is called the sidebar.

You can use the sidebar to display, for example, small preview images (thumbnails) of your current document. This gives you a better overview of multi-page documents and enables you to easily navigate between the pages of a document.

Using the sidebar

You can enable or disable a sidebar at any time:

To open a sidebar, choose the command View | group Window | Sidebars and select the desired sidebar.

To close a sidebar, click on the enabled option there again. Alternatively, close the sidebar by clicking on the x icon at the top right of the sidebar.

The small function bar directly above the sidebar provides you with additional functions of the sidebar.
