delpino,
I'm guessing you don't want GoTo...acPrevious, but a FindPrevious? Not a standard 'wizard' functionality. FindNext is always there, but you'll have to code your own FindPrevious. I'm thinking along the lines of saving the 'find next' results--putting the primarykey into a form-scoped array and then going backwards through the array.
Not perfect, but it should fill in if what you're wanting is for a user to hit a 'FindNext' arrow you've created, and then be able to reverse if he passed one up that he wants to review.
