This image shows the Expression Editor. In the header, it is labeled Expression Editor and provides a Help icon and a Close button. Two options are listed, "Choose a value," and "Type a value or expression." Below "Choose a value," are two menus, side-by-side. The first provides a selection list of categories from which to choose EL expressions (ELs). The second provides a selection list of expressions related to the selected category. Below "Type a value or expression," is a text entry field for entering an EL. At the bottom of the dialog are Test, OK, and Cancel buttons.
