Unable to type the shortcut Command-Shift-B on Yosemite On Yosemite (Mac OS X 10.10.4) I'm not able use the shortcut Command-Shift-B, while Command-Shift-&lt;another-letter&gt; works as expected.

I've double checked this in the Keyboard Viewer: pressing Shift, Command and B simultaneously won't show the B button as pressed.

That is, this is what I see when pressing the 3 buttons:



Same goes by pressing Shift-Command and then clicking the B in the Keyboard Viewer with the mouse pointer.

Is there any setting that might prevent the B from getting pressed?
