I see that edwin added '/activeclip/' to control the currently selected clip, instead of '/layer#/clip#/' and so.
That's not documented in R4 manual.
Is there an extended osc documentation, or a wildcard complete list?
Actually both are used. The best way to find OSC addresses is to use the Application OSC map feature. You would find /activeclip/ under the layer focus, and /layer#/clip#/ under deck focus.
