The shortcut parser mapped "=" to Key::Equals and the matcher only took
that exact key, while egui reports the numpad plus, and + on layouts that
give it its own key (and often Shift+=), as Key::Plus. "+" and "=" now
parse to one chord key, a recorded + is stored as =, and the matcher lets
a = chord take Key::Plus too (also next to the native macOS menu, which
handles only the chord as written).
