Description
Overrides the inherited method to put the dataset in an editing state if the user types Del or Shift+Insert.
KeyDown first calls the inherited method, which calls the OnKeyDown event handler. KeyDown next attempts to put the dataset into an editing state when the user types Del or Shift+Insert. If the memo control is not linked to a dataset, KeyDown discards the keystroke. Derived classes can override KeyDown to handle additional key combinations, but the inherited method should always be called.
