I See Index Toc Or Other Codes Instead. Scroll down to the Show Document Content section and uncheck the box for Show field codes instead of. The TOC of the docu Im working on is much more user friendly now thanks for sharing this.
Its very simple I expect you did a key combination that told Word to show field codes the TOC is a field. Suppose you want to have page numbers for just Level 1 and omit them for Levels 2 and 3. Typically a heading style has been applied to the paragraph containing the text or image and thus it gets reported in the TOC where the TOC is set up to display text in several levels of headings.
Its a wise move to fully update the TOC before sending a document out.
By allowing you to see the INDEX code in theory the application is allowing you to manually make some syntax changes to the index without having to go to the menus. Change that to whatever you prefer. If you have accepted the default TOC settings the field code you will see when you press AltF9 is. Table to the c parameter.
