New to the game. I did try to look up an answer to this question online and RR but no luck. I’ve been playing that action triggered abilities can only be performed if the investigator is in the location with the printed action triggered ability. Is this correct? Or, can those abilities be performed by anyone at any location?

Thanks in advanced

You can only activate such abilities if you are at the location in question, unless a card effect explicitly states otherwise. From the Rules Reference ("Activate Action", p.4, emphasis mine):

An investigator is permitted to activate abilities from the following sources:

• A card in play and under his or her control. This includes his or her investigator card.
• A scenario card that is in play and at the same location as the investigator. This includes the location itself, encounter cards placed at that location, and all encounter cards in the threat area of any investigator at that location.
• The current act or current agenda card.
