At a guess, these tables might be the message maps used with MFC and ATL
libraries. Windows sends numerous messages to programs that create windows.
That's how you get your input about mouse, keys, etc. Message maps are used
to associate each message with a particular function. So when a message
comes in your function designed to handle it gets called, via the lookup
table.
