I've been working on a Visual Studio Editor extension that makes heavy use of IOleCommandTarget and the editor command chain. On QueryStatus() one of the CommandChainNodes is returning (uint)13 within OLECMD[] prgCmds.
According to this page this represents the flags OLECMDF_SUPPORTED, OLECMDF_LATCHED and OLECMD_NINCHED.
OLECMDF_NINCHED is marked as "Reserved for future use".
Does anyone know what this flag represents and when it would be set?
