Say a creature owns multiple items with wording similar to this:

> 
> As an Action, you may speak the command word to [...]
> 
> 
> 

Say the creature has deliberately obtained such items, perhaps by creating them itself, to have the same command word.

**Can this creature use one action to speak the shared command word and activate multiple items at once?**
