Rather than the language used, perhaps the interface would give the proper contextual cue: * Use a button interface for all actions the user can take: [send][archive]. * Use a link for nouns / places the user can go: inbox | archive | trash. * Icons tend to be actions (a star for 'mark this as a favorite', a trash can for 'delete this thing', a paper+pencil for 'edit this entry'), so they get grouped more with the buttons.
