Solved button

How can I get the solved button when a moderator or me edit a topic and you press a button which puts '[solved]' in the title. Or do you just have to write it in. I think it's possible, that's why I asked. I put that in a lot of the time in my forum.

Me thinks you have to write it in - I have never seen such a button on any forums before!

hmmm, ok... It just gets annoying when I have to write it in a few times a day.
