Yes, but my key command for view (page view) is command-alt-&, not shift-alt-& (in my french keyboard, you need to do shift-& to get 1). If I open the preferences > Key commands editor, and add aalt-shift-& for page view, the program does not tell me anything, which means it is not used by it for something else — at least nothing that the command editor can handle. But it does not accept either, certainly because it is a dead key.
