HTML Code Indexing A new addition are the Index submenus under the Anchors, Heading and Font popUp menus. Selecting an index command displays all instances of the selected HTML code within your document. This is displayed in a text field that overlays the main document window. Once done with the index, you can close it by clicking on the close box of the document (not the stack itself). This close box only appears when the index field is visible. Note that you can select and copy text from the index field. Back to Tool Palette, on to File menu, or return to Contents.
