@jcsteh, should Accessible2_3.idl be included in build tools? It doesn't exist in concatidl.sh.
@michaelDCurran, I'm trying to add the IAccessibleTextSelectionContainer interface into NVDA. There is a compile error. I want to synchronize NVDA scripts with that of this repository. However, I'm not sure if there is a change that needs to be made here.
