Setting the focus to the Subject Line

Hi all - has anyone found a way how to set the focus to the subject line instead of the body when exiting from a message box or userform? I've been googlng but so far had no luck. :dunno

Cheers,
rrenis

EDIT: By the way I'm using messages in Outlook Rich Text format - not Word (which I guess would be easier to set the focus). Thanks for looking!
