Re Word 2021 (bought version of Office 2021 Professional, not subscription) and Windows 10: same issue. First tried assigning Ctrl-PgDn to "GoToNextPage. Got "This command is not available on this platform." Tried Shift-Ctrl-PgDn. Same. Thoughts. Besides, what happened to the little pop-up thing that used to be on the lower right side of the screen which allowed selection of the BrowseTo object?
