Polyline Arc - move arc to other side

I'm making a polyline arc and would like the arc to go the other way. What button do I press to make that happen? I stumbled upon it one day, but have forgotten the button. Anyone know?

When in doubt, always look at the Command Line

Specify endpoint of arc or
[Angle/CEnter/[b]Direction[/b]/Halfwidth/Line/Radius/Second pt/Undo/Width]:

Alternatively may draw the polyline by his simple entities (lines and arcs) and use next PEDIT command to join them. This way you will have better control over arcs.

Or what I usually do, just draw a polyline with 'default' arc and edit it using grips when I finish the whole polyline. Since AutoCAD 2011 you can forget about arcs drawing polyline, because you can convert line into arc using just grips

PS. Don't forget about JOIN command with the newest AutoCAD.

Yeah, I had checked the Command Line, but it hadn't help?

This works well, thanks.

You're welcome!
