Unexpectedly found some extra keyboard shortcuts for Find Next and Find Previous functions in Microsoft Word 2003. The online help only lists Alt+Ctrl+Y for Find Next and no shortcut for Find Previous. You can also use Ctrl+PgDn for Find Next and Ctrl+PgUp for Find Previous. Bonus!
Later … Julian W. pointed out that this is part of the Browse Object feature. Press the circle icon below the page's scroll bar or type Atl+Ctrl+Home and Word displays the Browse Object panel. Select the object type you want to browse, e.g. Browse by Heading, then press the double-up or double-down arrowheads in the scrollbar to go to the previous or next object (in this case, heading). The tooltip displays the keyboard shortcuts, which are Ctrl+PgUp and Ctrl+PgDn, respectively.
Even later … Found Microsoft reference.
