Thanks for the positive reply Marti. When you say soon, do you mean a few months, or do you mean whenever the new input system is in an LTS release plus a few months?

Solved. I was using On Key Pressed instead of On Player Enter Key. I would suggest that any action which has player input at its core should be in the input category, since it was not at all evident that this trigger type would exist somewhere else.

I was able to get this working by deleting my trigger and recreating it, however now if I set the trigger to key down, the trigger activates no matter where I am in proximity to the object. Looking through the conditions don't see an obvious way to check how far the player is from a trigger.
