The Workbench supports OLE document editors.
Select JanesFolder in the navigator.
Notice how the Workbench automatically opens the OLE document editor in place and integrates its pull-down menu options into the menubar. There should also be an editor tab for JanesWordDoc.doc.
Make a change to the file.
Close the editor by clicking the X on the editor tab; when prompted, save its contents.
Reopen the file by double-clicking it in the Navigator view.
