Hello everyone,
I've had problems discovering the feature of dragging button 1 to scroll
the tag line.  I have used first the p9p's acme, which has a more natural
way to manage the tag line, so I thought I was missing something.
I have been looking in the 9fans archives and I found the trick.
Then in abaco, when a text box was full and a strange picture appeared
(again) on the left, I said Why not? and voilà! this works here too,
and the picture turned out to be a scroll bar.

Yes, for you this could be a silly question, but for a newbie like me is
not.  IMHO, those things must be in the man pages.

Regards,
trebol.
