In Visual Studio 2005 and 2008 you used to be able to mouse over the toolbar and a tooltip would pop up showing the associated shortcut key if you turned on the feature. This feature seems to be missing in VS 2010.

Suzanne Hanson from Microsoft indicated in a post that for 2010, this feature would not be configurable and would be turned on by default. http://connect.microsoft.com/VisualStudio/feedback/details/489554/toolbar-icons-tool-tips-missing-shortcut-hint.
Does anyone have this feature turned on? Could it just be that my Visual Studio Version is out-dated? (Help -> About reports Visual Studio 2010 v. 10.0.30319.1 RTMRel)
