Haha, never thought about that.. but, I don't think so. Doesn't work in IE, it never tabs into those. What would you use a negative tabindex for anyway?

I'm inserting another page (actually using a tiles:insert tag) that has tabindexes starting from 1, and I'd like to have things, in the original page, before the insert tabbable. So i guess I'm...

Well, the good news is that the tabindexes don't have to be exactly sequential. You can count by fives or whatever. They'll always be tabbed to in ascending order.
