In Word, you can use Cross-reference to refer to specific places within the document. Insert captions lets you label objects, figures, tables, equations.

Create the cross-reference. Within Word, a cross-reference is a link to another part of a document. It’s actually a field, { PageRef }, and you can enter and update it as you would any other field.

Start Word and open the document with cross-references that you want to update. Click anywhere inside of the document. Press "Ctrl-A" to select the entire document.

With an index, finding topics in your Word document becomes a smooth scroll instead of a needle-in-a-haystack hunt.
