Summary: OODialog VirtualKeyCodes Class Alt-Ctrl-Shift Key Combinatio

Initial Comment:
At the moment, the Virtual Key Code Class does not 
distinguish pressing a single key or pressing a key in 
combination with ALT (or MENU as it is called), CTRL or 
SHIFT.  

At least this is certainly the case when it is used in 
conjunction with the KEYDOWN event of the 
ConnectListNotify Method of the MessageExtensions 
class.  It would be INVALUABLE to be able to distinguish 
these key combinations.

At present you get a notification of the pressing of the 
(for example) MENU key and then a notification of the 
key pressed in combination with it.

I suppose for backwards compatibility one would need an 
optional parameter to request these key combinations.

Committed revision 7443.

I added a keyword notification, KEYDOWNEX (Key down extended) that sends as
arguments to the event handler all the information known at the time the
notification is sent by the list view.

This does not change the Virtual Key Code class, there is no such thing as
a virtual ctrl-C or alt-F key code.  Rather when the notification arguments
are sent to the Rexx method they include arguments that tell whether the
Ctrl, Alt, Shift key are down.  So, if the user presses, say Alt-F, you
will still see a notifcation when the user presses Alt, (MENU key,) and
then a different notification for F, that's the way Windows works.  But,
when you get the F notification you will have an argument that specifies
that the Alt key is down.

By the way, ooDialog 4.2.0 includes the .VK class as a replacement for the
Virtual Key Code class.  The .VK class includes every single virtual key in
Windows, rather than just some of them.
