as defined by the key code constants in class <code>SWT</code>.
When the character field of the event is ambiguous, this field
contains the unicode value of the original character. For example,
typing Ctrl+M or Return both result in the character '\r' but the
keyCode field will also contain '\r' when Return was typed.
