Create action for selected tags

I'd like to create an action that only affects the tags 'artist', 'album' and 'title'.
Do I have to create the same action three times, or is there a way to include multiple tags in the 'Field' box ?
I tried some separators (like semicolon and slash) but they don't seem to do the job...

Unless you want to delete tags completely, or apply an action to _all you have to create the an action for every field.
But you can create an action group so that you have to call an action only once. Once you have set the name and created the action for the first field and you return to the action-type-selection dialogue you can either copy the previous action or set a completely new one. If you define an action group like that, actions are executed in the given sequence from top to bottom.

OK, thanks.
