Description
Supplements the inherited KeyDown to process navigation keys and the Delete key.
After calling the inherited KeyDown, KeyDown ensures that moving the cursor within the masked edit control places the cursor on an editable character, and that deleting the current selection replaces nonliteral characters with blanks. Derived objects can override this method to further supplement the processing that takes place when the user presses a key down.
