[Scribus] Drawing curved lines

[Gregory Pittman]

Something I have never mastered is how to use tools such as in Scribus 
for drawing curved lines.  In the various pieces of software I've used, 
I never seen a description of how your "supposed" to be able to easily 
draw a Bezier curve.  Even just drawing a simple arc, mine always seem 
to go the wrong way -- eventually I can fix them with editing, but for 
me it's a tremendous effort. 

Is there any help out there?
