Calibre 3.0 breaks non-modified keyboard shortcuts

[Phillip Winn]

Before the upgrade to 3.0, I used the custom keyboard shortcuts 'A' and 'B' regularly. Immediately after upgrading to 3.0, I realized that these no longer work. I can use 'Cmd-A' and 'Cmd-B' but that conflicts with existing functionality I also use.

When I do that, however, I notice that unmodified 'A' and 'B' navigate within my book list, a feature which disappears when I map 'A' and 'B' to shortcuts.

I notice also that 'C' still works as a shortcut. I haven't mapped out which keys work as shortcuts and which don't; I just know that 'A' and 'B' don't.

I'm running MacOS Sierra 10.12.4.
