Actually in Thunderbird space bar without Ctrl also works but only for selection, un-selection requires Ctrl + space.
I'm wondering why it does require that...?
What happens in Thunderbird if you press space on a message which is already being selected? Nothing? Or does it get un-selected?
Well, on already selected message it has a complete different meaning. It does not unselect the message. What's more it scrolls message content in preview frame. When it's at the end of the message body and scrolling is not possible it jumps to next unread message. So, Thunderbird uses space bar as "scroll to end or open the next unread message".
