1337 Translator

I am making a program that will translate words like this into w0rd5 1!k3 7!k3 7h!5. All I really need is the little chunk of code that makes the I-Beam (cursor) move to the very end of the textbox. Also, I want to make this program global - so you can type in any textbox in any program and it will automatically be converted to 1337. (I would have a system tray icon too) But if anyone has any suggestions how I could integrate it into Windows or something like that, it would be very helpful as well. ## Deliverables Nuthin! Just as much as you can tell me... ## Platform Windows, any version
