Program to type faster. Guess word from first letter.

[jwr18]

Back in the DOS days I used a program(with sip and puff morse code device) that would display a list of words by inputting the first, second or third letter. Then you could choose the word without having to type the rest of the word. I guess its being used on mobile phone for fast messaging. It would help to speed up typing and with my atrocious spelling but not for my bad grammar.

I need it for XP/Vista.

Thanks
