I know that gray square brackets can be displayed for bookmarks (cross-references).
"Show bookmarks" under "Show document content" on Advanced dialogue is clicked. There are many cross-references in the document, but somehow those square brackets don't show up.
I don't think this matters, but "Always" for "Field shading" under "Show document content" on Advanced dialogue is selected.
Is there anything else I have to click.
I use MS Word 2010, but I've tried this with MS Word 2007 at home as well, but no luck.
