Visual Studio :: Format Document Button In 2010?

One button I always had on the 'HTML Source Editing' toolbar was Format Document, as found in the Edit menu, however in VS2010 it isn't visible. If I go to add it, it doesn't exist in the options.The toolbar currently holds Format Selection, Decrease Indent, Increase Indent, Comment, Uncomment, Schema and accessibility.I bring up the Customize dialogue box (Add or Remove Buttons/Customize), then in the Commands tab I click Add Command... In the Add Command dialogue box, I choose Edit from the categories list on the right and yet in the commands list, Format Document isn't there anymore as it was in VS2008.Yes I could just use the Edit menu command, or even the keyboard shortcut, but that's too long-winded and the toolbar button is now sorely missed.Has this been somewhat arbitrarily removed from VS 2010 or is it hidden elsewhere?
