Custom keys for rexxar

Honestly, there’s a part of me that wants to write a very different kind of message right now about the utterly shameful state blizzard released this in, but it seems like the rest of the internet has me covered on that front. So, instead, I wonder if anyone might be able to help me enjoy what little they did offer me for my money. Seems they couldn’t be bothered to so much as build a key binding menu in 2020 so I have to use the antiquated custom keys file, which at least they gave us this time instead of forcing us to make our own. Only Rexxar isn’t in it. There’s a beastmaster, but the abilities are different and the code clearly doesn’t apply to him. So, and I really think this isn’t a very big ask all things considered, can anyone tell me how to add Rexxar to custom keys?

You may want to try this in the GD forum where players may have experience with custom hotkeys. Using game features isn’t really in Technical Support’s wheel house.
