Notice with continuous forms, typically the arrow-key behavior is nothing like that of a regular spreadsheet or datasheet. When you press the down-arrow key, you jump to the next field rather than to the next record as you would think. Same thing with the up-arrow key. There is a way around it, though, in this code derived from the Access 2000 Developer's Handbook, Volume 1, Chapter 8.
Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer)

Case vbKeyDown
DoCmd.GoToRecord Record:=acNext

Case vbKeyUp

HandleErrors:
Select Case Err.Number
Case 2105
KeyCode = 0
Case Else
MsgBox "Error: " & Err.description & _
" (" & Err.Number & ")"
End Select
