- Global Shortcuts (like in Visual Studio)
- Macro recording, both the start/stop shortcuts, and the recording of inputs
- Automation
- hacks
- unknowns

For a framework, hacks and unknowns are valid reasons.  The reason I
detest MFC is because it was inflexible beyond anything more than they
had planned for.  ie standard UIs were easy, anything else was near
impossible.

I know that any framework that did child first ended up needing a
parent-first hack, and anything that was parent-first needed
child-first sometimes.  Unfortunately I can't remember the particular
reasons, but it seemed to always happen.

I do agree that events should go to the child first almost always.
It's those other cases that I'm concerned about.
