Learning Morse Code

it's occurred to me that in this age of Text Messaging people have forgotten the old ways of wireless communication. What would you do if the main lines that currently carry your Text Messages, IM's and Emails were to suddenly go dark? The easiest thing to do would be to fall back to using Morse Code broadcast over radio waves. While the above scenario is unlikely, it has been proven many times that sending messages using Morse Code is faster than even the most practiced Texters so why not learn it? I know I'd like to be able to press as few keys on my phone to create and send a message as possible and in keeping with the small form factor of many devices today Morse Code seems a perfect fit (only requiring one button). In an attempt to make learning Morse Code easier I've started working on a Morse Code trainer Application (will post details soon) and here's a list of my current compliation of known Morse Code sequences (for timing, consider a '-' (dah) equal to 3 '.' (dit)):

THE ALPHABET

So, go ahead and give Morse Code a try...
