`published property TDBGrid.OnKeyDown : TKeyEvent;`

## Description

OnKeyDown is a TKeyEvent event handler signalled when a key is down while the control has focus. OnKeyDown is called from the KeyDown method when processing keys specific to the data-aware grid.

OnKeyDown differs from OnKeyPress. With OnKeyDown the key may have already been down when the control receives focus. With OnKeyPress the key needs to become pressed while the control has focus.
