Automatic Save for Notepad

I use notepad a lot for when I am mudding. However occasionally something happens and I lose everything in notepad. I like it for it's convenience but it doesn't automatically save, Some documents I don't mind if it does this, but I'd really like some way of having it automatically save those files.

Make a timer that calls SaveNotepad every few minutes (for the name of the appropriate notepad(s)).
