The editor keyword lists apparently don't quite keep up with the releases. If you run into a keyword that shows up as undefined you can add it to a list of user defined keywords to eliminate the annoying red. With the enhanced editor window active go to Tools > Options > Enhanced Editor > General. There is a button on the lower left labeled "User Defined Keywords". Click on the button and use the Add button to add words to the user defined list. You may also want to go to the Appearance tab and change the settings for User defined keyword by selecting that in the "File Elements" list.
