"Bookmarks" Within a Worksheet

Good morning, all - I'm new here, so please forgive if I make any forum faux pas!

I have an extensive spreadsheet (within a larger workbook) with three distinctive points to which I return frequently. Is there any way to mark these points and set some kind of shortcut key for quick return so I won't have to continually scroll to get to these points?

Many thanks in advance to anyone that can assist!

Best regards,
