Add the macro to your Normal template's 'ThisDocument' code module. Implemented that way, the macro will run every time you open
any document. When you're not wanting to mark students' work, you might consider changing the macro's name to something else (e.g. FmtBlnAndCmnt) so it doesn't run every time you open
any document. Renamed, it will only run if you select it manually.
