Today I found out about the Visual Studio Clipboard Ring, which keeps the last 15 entries that you have entered into the clipboard using copy and cut (CTRL+C, CTRL+V, SHIFT+DEL), and lets you paste into the Visual Studio Editor an item from that list.
You just press CTRL+SHIFT+V when pasting, and each successive press will cycle through the entries. Very useful if you kept something on the clipboard, but then pressed SHIFT+DEL to delete a line, forgetting about what you wanted to paste! Which I tend to do a lot!
