Hey Dan,
the link_knob is a knob that get's created, when you pick a knob from the
manage user knobs dialog for example. As you mentioned, it than simply links to
that knob in the group/gizmo.
I started collecting some knobs, that make problems for something else, but
there might be some that will not take animation either here's a list:
("Obsolete_Knob", "IArray_Knob", "Tab_Knob", "BeginTabGroup_Knob",
"CascadingEnumeration_Knob","GeoSelect_Knob", "RotoKnob", "EndTabGroup_Knob",
"Link_Knob", "Keyer_Knob", "Menu_Knob")
cheers,
Patrick
