position your mouse pointer on the tabs and just scroll left or right. you have to have LOTS of tabs to do it.
Before I test this myself do you know the exact number of tabs you need?
What a let down. I see what it means now.... not scrollable tabs at all. I thought this would replace CONTROL+TAB and CONTROL+SHIFT+TAB but no. It just shows you which tabs are open it doesn't change the tab you are on.
what did you think that was? there's a nice bird view of all tabs if you click the button next to downloads. what did you expect exactly?..
funny, I thought it would work how the OP described it, that you can actually go from one tab to the next with that gesture. someone should invent that!
