Kindly asking for help

I have a HTC CHA CHA and while I was writting a text message pressed the letter S key and instead of typing the letter, send me to drafts messages. does anybody know how to fix it? is it possible I pressed it too long and now it's like a shortcut for saved messages in drafts?

Thats weird. So anytime you press the s it does this? Have you looked in your SMS settings to make sure all are normal?
