This is just for fun.
I'm playing a game where you type A-z as fast as you can, I can't do it faster than in 5 seconds and I think it may be humanly impossible to do it in 1-2 seconds. However, it may be possible to create a small program in Java or Php which, when started, sends the inputs of letter keys A-z to the computer as fast as possible.
How can this be done in either Java or php?
