Well, I finally made the time, so I'm sharing what I found here. Maybe it will help someone.
First, you have to enable the international version of the keyboard. That part scared me and I had to read up about it. Anyone who has ever typed on a keyboard in Europe knows what I mean! I didn't want to end up with all my keys scrambled. But you're just adding an option, and it's a US International keyboard, so it's just adding, not scrambling. Whew! Here's how you do that part - Adding the US - International Keyboard in Windows 7.
It will add a little keyboard icon to your taskbar. Click on this keyboard to expand the options and you can choose the US - International (or go back to plain US) any time.
Now, when you're typing anywhere - in any application, or in a browser, you just have to enable your international keyboard. Once you've done that, the key commands are easy! Here they are:
Note that you don't hold down the first key. Type one, then the other. Hope this helps someone.
