Hidden Features of Visual Studio (2005-2010)?

Answer 1

You can drag code to the ToolBox. Try it!

Answer 2

CTRL-K, CTRL-D

Reformat Document!
This is under the VB keybindings, not sure about C#

Answer 3

Ctrl-Minus, Ctrl-Plus, navigates back and forward where you've been recently (only open files, though).

Answer 4

Document Outline in the FormsDesigner (CTRL + ALT + T)

Fast control renaming, ordering and more!

Answer 5

Click an identifier (class name, variable, etc) then hit F12 for "Go To Definition". I'm always amazed how many people I watch code use the slower right-click -> "Go To Definition" method.

EDIT: Then you can use Ctrl+- to jump back to where you were.

Answer 6

CTRL + Shift + U -> Uppercase highlighted section. CTRL + U -> Lowercase the highlighted section Great for getting my SQL Statements looking just right when putting them into string queries.

Also useful for code you've found online where EVERYTHING IS IN CAPS.
