Side note--if you want tabs to be able to leap around a long document
easily, Word does have several built-in options to speed up navigation:
Edit | Go To, Outline View, Document Map, and Browse Object.
.... Or if it's just a matter of going from page to page what's wrong with
Ctrl+PgDn/Ctrl+PgUp? Or - for a mouser - Daiya's suggestion of the Browse
Objects button (bottom of the vertical scroll bar)?
