In Visual Studio 2008, you could turn on the keyboard bindings to be displayed with the Tooltips. For example, if you hover over the save icon, you would also see CTRL+S. This was tip #64 for 2008, but seems to be missing from 2010. And I looked in every place I could, including the registry.
Now it’s possible that these can still be turned on somewhere, somehow, but I can’t find it. Maybe it was excluded because of performance? Maybe it can be programmed as a custom Tooltip Adorner? I don’t know, but maybe with this post, we’ll get an answer from the team.
