Running 5.0 SR4 on Mac 10.8.2
When I (press Cmd-G and) type a reference to browse within a book the focus remains on the reference box with the effect being that you can't navigate the book with the keyboard. I keep having to use my mouse 
If that is the intended behaviour, it would be nice to be able to tab or escape out of the box to then navigate with keyboard...

ps. loving all the keyboard shortcuts in L5, are there new ones, or did I just never discover them all in L4?
