Change Details

Some user experience feedback... When editing http://en.wikipedia.beta.wmflabs.org/w/index.php?title=Related_test I saw a large dialog asking me if I wanted to always use wikitext editor or VisualEditor. I think I dismissed it as I was rushing at the time ... I forget... I just wanted to edit in wikitext. Now 5 minutes later I want VisualEditor and I have no idea to get to it. I vaguely remember something about tabs in the dialog but I can't see some tabs anywhere and am feeling pretty stupid...
