Yea, I found TComponentPalette.UpdateNotebookButtons on my own in a round
about way. I  set a breakpoint in TControl.SetHint and launched an instance
of the IDE with the debugger attached. After a half dozen hits I was into
the pallet speedbuttons and checked the call stack.

Now I'm trying to track down how the source editor invokes FPDoc support
when you hover over an identifier. A search for FPDoc in the source turned
up the CodeHelp unit. Anyone know if I'm on the right track?
