How to simply select loop of connected sketch entities (lines/curves)?

Rhino
1

I’m trying to extrude a perimeter of many sketch entities.

Everything is on one layer one color and much clutter.

There must be a way to select one of the many entities of the perimeter then tell it to select all entities in the chain, rather that picking all 100ish entities.

FYI motive in this case is the perimeter is not closed and it’s not obvious where the connection is missed. In solidworks I would right click one and then click select chain, and that selection would show me where it’s non contiguous, which is my secondary goal here.

Found it, “selchain”, found it on the select tab duh haha.
