A menu bar, submenus and menu items are views. A menu item's items are an
ItemsControl's, so they are patched as a list's. A context menu wraps a
view: the view and its menu are two places of the wrapper.
Keys are matched in the window's KeyDown, after the focused control had its
chance: an enabled menu item in the view whose shortcut it is, or else the
app's #:keys. Avalonia's own key bindings take an ICommand, which a Bjolang
program cannot make. app-press! presses keys for a test.
