Shift+NumpadX shortcut keys not working

Hi Michael,

I was just assigning some new shortcut keys and discovered that "Shift+NumpadX" keys don't work. Alt and Ctrl prefixes work fine with the numpad keys. Is this by design or is it a bug/problem with my installation. Not a big deal as I can use Alt prefix just as easily, just thought I'd ask. Thanks.
