Bill,

Seems like you've gotten a few replies, but here's how I've done it since VFP 3.

In the valid of the last column I put something to this effect:

IF DoDefault()
Thisform.MoveNext &&--Method built into my forms
ENDIF

The trick is to have it only happen for keys the user would press, such as TAB, ENTER, the numbers, or letters. You run into trouble unless you check for specific keys

MyFormClass.MoveNext
IF INLIST(LASTKEY(),13,48,59,50...) OR...
  SKIP
  IF EOF()
    FrameWorkMethod.AddRecord()
  ENDIF
ENDIF

Hope one of the approaches works for you.
