Grid Cursor Move
This Config statement helps with grid cursor movement (4.2+):
GRID_CURSOR_MOVE DOWN | RIGHT | NONE | DEFAULT
This determines the field cursor position after keying Enter or Field +/-. Both navigation and edit mode produce the same resulting cursor position.
Default Enter and Field +/- cursor movement are unchanged. Field plus or minus perform a down arrow operation, and Enter defaults to DOWN. GRID_CURSOR_MOVE overrides both of these.
