How to change a Kopete shortcut?(break line)

[aeav]

I have a doubt.. When I pres the keys Ctrl+Enter at Kopete(using MSN protocol) it give-mes a break line, when I'm sending a message. I don't want this combination, I want Shift+Enter to a break line. Some one knows how can I change it?

I already search at all Kopete and nothing that I would chance this keys..

thanks
