bookmarks ...
What is it? How will it help me?
It takes a string of text in your document and gives it a name. For
example, you can use:
Edit >> GoTo >> Bookmark
to jump around in a big document from one bookmark to another.
Different people use bookmarks for different purposes. For example, you can
use bookmarks along with fields for numbering figures and having references
to them by number (e.g., "See Figure 3 for ..."). If figures are inserted,
or rearranged, Word features can update the references without you having
to keep track of it all manually.
Why doesn't it show on screen?
Try
Tools >> Options >> View
and under "Show" check "Bookmarks". Then, square brackets indicate the
bounds of each bookmark. (These square brackets don't print.)
