bumped update to 8a0b961f9d45:
Allow individual applications to define their own shortcut mapping
When a system wants to translate a shortcut into a logical action key,
the event bubbling process ends up asking an application model for its
keyboard map.
To allow per-application customization, each application model keeps its
own keyboard map initialized from class defaults.
