The same folks who developed MathRun have also made an online keyboarding speed test site called Ten Fast Fingers.
On your screen you see some words, and a space in which to type. Use 10 fingers on your keyboard, and copy the words. When you're finished, you'll get a report of how you did:
Use the little flags at the top of the page to choose which language you want to practice keyboarding.
And you get a badge that tells you your wpm (words per minute) keyboarding speed.
