Good to know it works. The keywords are indeed standard, however Clang itself has a fairly complex logic for suggesting different keywords based on context, that changes from version to version. And since it is maintained by the Clang team, we want to avoid making major changes to it, hence we added a very thin layer on top that unconditionally adds the keywords specified in the settings in case Clang does not suggest them yet (we do check for duplicates, so no worries about that).
