Newbie question for VFP6:

After devouring several books, scouring the Codebook6.1 framework, and looking over the FPD2.6 and FPW2.6 code (probably what is confusing me) that makes up the apps we are currently running, I still don't quiet understand how to set a form so users can browse existing records and then unlock the records for editing. New, Save, Cancel I've got a handle on OK, but can someone point the way to edit nirvana, I don't mind the rigors of the journey, I'm just not seeing the path.

With humble thanks to all you knowledgeable ones.
