How to temporarily disable Automatic Login

A great tip submitted by Vagnard: How to temporarily disable Automatic Login. Automatic login is great because it is really fast. I use it on my laptop because I am the only one using it. If you want to keep automatic login enabled because you nearly always use the same account, but sometimes want to login into another and not wait to change account until it is loaded, temporarily disabling it is the best option. It is also a very quick shortcut: "Shift - Option - Cmd". To get the login window, you just have hold down that shortcut when going from the grey Apple logo to the light blue screen until the login window appears. Of course, it only works if you have more than one account. Thanks for the tip Vagnard!
