IMO it's not intuitive though. eg. on a 2-part popup intro(warning+gameinfo), pressing Tab once does not work, the first Tab skips the warnings popup. It would make more sense if it opens the Tab menu rightaway, and when you close it, go back to the same popup instead of starting the game. Name the return option "Return to Machine" like usual, now it looks like it's a different menu. And re-add "Select New Machine", but grey it out.
