How about a middle ground: create a new TKeyboardEvents unit using
code from one of the components that already has it. Yes you will have
the initial code duplication in creating the unit in the first place,
but this would allow adding keyboard events to other controls simply
by inheriting from the base class. In fact, this may be something that
the LCL could use and incorporate itself in the future, if you get it
working property.
