Hero carries item?

I need a trigger that can check if a hero is carrying an item, but it doesn't have to be any certain item. In other words, I may have two or three of an item on the screen and they could acquire any of them, so I want the trigger to just check if the unit is carrying an item of that type, it doesn't have to be even those that are created. The trouble is, I create these items at different times and for different units, so it'd be easier to just check to make sure the unit has this item type. Any help would be appreciated.

blah...never mind, I found it. I fell stupid now. Delete post if you wish.

Ok, while this is here, let me ask this. Is there a way to pause a trigger? I'll give you an example. One person uses an ability. The other person then gets the option of stopping the ability from being cast or to let it simply go through. Based on the decision, the spell could complete through the trigger or, another trigger could run, canceling the first one. Any ideas on a good way to do this?

I think it is possible. There is a stop trigger quene or somethin like that. Check it out and tell me
