• Dragging-and-dropping code onto the toolbox's General tab.  Discovering this was revolutionary.  Whether it's code that I use infrequently (e.g., an implementation of the IDisposable pattern) or something that I know I'll need to insert several times in the next few minutes, it's handy.
• Keeping recently used files from falling off the file tab channel.  Oh, how I hate to have to find the file I was just using in a dropdown list or Solution Explorer.  This keeps files ordered by usage rather than the order they were opened...and saves my sanity.
• Pressing Ctrl+D opens the Code Definition window.  Until I read this tip, I didn't know there was a Code Definition window.  I love being able to view definitions and declarations without leaving the code I'm working on.
• Searching for the currently selected string without bringing up the Find window.  Now the Find window can't cover the code I need to look at.
• Viewing your project in the Document Outline window.  I no longer have to scroll through the dropdown in the Properties window to find that control that missing control.
• Displaying external function names in the Call Stack window.  If, like me, you do a lot of managed/native interop, this is invaluable.
• Selecting a box of text.  Great for indenting columns in the middle of a table of data.
