How to select a segment of a polyline?

How should I select a single segment of a polyline?

Thanks

I’m not 100% sure if this works on polylines, but try Ctrl+Shift to activate sub object select.

ExtractSubCrv will extract a single segment of a polyline or polycurve. http://docs.mcneel.com/rhino/5/help/en-us/commands/extractsubcrv.htm

Thank you both very much !!
The option of Ctrl+Shift doesn’t work.
The ExtractSubCrv command works fine.
Thanks

This works in V6/WIP, just fyi, but only as a selection within a polyline, not to extract the segment.
