Any good keyboard extenders?

[veritas]

Anyone know of a good program that lets you type in a long word or
combination of words/numbers by making a user-defined abbreviation for
it, like autotext works in Word, so you could type zm to type an address
like 45 Knickerbocker Ave., for example. I tried Keyboard Booster for a
while, but it's confusing to use (The directions were obviously written
by someone with a poor command of English)

There used to be an application called Quickeys that I used a lot. It is
probably gone.
