It means that the accelerator emits the same event that is send
when a menu item is selected and not the event sent when a button
is clicked. This turned out to be very easy to fix in wxGTK.

Moreover, I realized that you don't, in fact, need to handle
EVT_BUTTON(wxID_HELP) in MvcController, because wxID_HELP handler
is in Skeleton, so it just has to handle wxID_HELP button events too:
