Window layout
          The Formula Designer window is split into three areas:
         
         - Formula Variable pane
 - Formula Edit area
 - Formula Display area.
 
Formula Designer displays a toolbar, which allows you to access the functionality also accessible from the menu bar. Once Formula Designer is open, the Formula Variable pane is populated with variables which are displayed in a tree-like structure.
All dialog boxes within Formula Designer are resizable. Drag any edge of the dialog box to make it wider or smaller.
