          | When opening a Type Hierarchy | 
              Note: On the Workbench preferences page, you can choose whether new perspectives open in a new window, in the current window, or as a replacement for the current
            perspective.
                Open a new Type Hierarchy Perspective
              
                  Opens a new Type Hierarchy perspective whenever a Type Hierarchy view is opened.
              
                Show the Type Hierarchy View in the current perspective
              
                  The Type Hierarchy view is displayed in the current perspective.

          | Refactoring Java code | 
              
                Save all modified resources automatically prior to refactoring
              
                  If this option is turned off, refactorings may prompt to save modified files if required.
                  If it is turned on, all modified files are saved without prompting prior to opening a refactoring wizard.

                Rename in editor without dialog
              
                  If this option is turned on, then the rename refactoring will not show a dialog if invoked inside a Java editor.
                  Instead the new name for the element to rename can be typed into the editor right away.

                Enable new Java index
              
                  If this option is turned on, Eclipse will build and use a new index for
                  accelerating many Java operations. This will reduce the number of UI freezes but
                  will consume additional memory and disk space.

                Rebuild Index
              
                  Pressing this button will delete all information cached in the Java index.
                  This can be used to save disk space since the rebuilt index is often smaller
                  than the original. It can also be used to fix index corruption in cases where
                  types appear to be missing from the UI.
