For anyone who uses Windows... you guys all know that Windows has a pissy clipboard that can hold ONE THING AT A TIME! How useless is that?
Get ClipX (http://www.bluemars.org/clipx/), it's free, it's fast, and it allows you to have unlimited clipboard "slots" where you can copy copy copy copy copy, then paste a specific selection later on.
Copy as normal with CTRL+C but when pasting press CTRL+SHIFT+V and you get a nifty menu of all the copied items you have.
I set this thing to run on startup of Windows, and I find it VERY HANDY!
