Shift-A not Working in 3.0

In Calibre 2.84, it was easy to add files to an existing record by selecting the record and typing Shift-A.

In Calibre 3.0, on the Mac, it is no longer working for me. I can go through the menu, but it was a lot easier to use the keyboard.

I know the Mac has keyboard integration problems... bugs with Sticky Keys and complete failure with combinations of physical and screen keyboards.
