Exit key on remote

[MCHellspawn]

Hi,

Hoping you can help. I'm using an integration to my TV in my home automation system, Home Assistant. This integration uses this library in the backend. I have a somewhat newer TV (2ish years old). My remote has an "Exit" key on it, I'm not able to find that key in the list. I tried KEY_RETURN but it isn't functioning like my Exit key. Wondering if you had any ideas.
