I think this is basically what I want:
_dupedge
_pause
-grasshopperplayer “W:_Resource Library_Grasshopper Definitions\mirror_x_srf.gh”
_pause
_selprev
_delete
However the _selprev is giving me the output from GH, not the input curve I am trying to get rid of. I am trying to select 2 objects ago basically I guess.
