How do I make a character-specific key bind?

[Aurorance]

I am a beginner at modding in this game, and I have look through lots of newcomer post / tutorials about modding. So far I have learnt how to add basic perks to my character (let's call it Gojo here).

The main question I want to ask is : How can I add key bind to my character to trigger a specific skill?

I didn't see any posts in the forum asking about this so I choose asking here. Hope this helps other people who shares the same question.
Currently, I want to make everything as simple as possible first - When I press key G, Gojo deals AOE damage around himself.
Press G -> AOE damage (e.g. to all living entities)
(I don't need to set up any cool down for this skill, key configurations or animation stuffs, I want to make this as simple as possible for my learning.)
I have asked some questions in other posts, and I gained some advice from Ultroman, who teaches me how to make AOE damage.

But one thing - How can I combine it with key bind?  (I have tried OnKeyDown and keyhandler in my character file below, but pressing G doesn't work.)

I have also downloaded some character mods from the workshop (that deals AOE damage with keybinds) like Carney or Amelia Watson. However, the mod file is very complicated, and the chunks are connected each other (like animations), which makes me cannot find out which part is related to the key bind part.

For convenience, I have attached my whole character zip file here. I hope someone can have a look at that and tell me where the problem is, thanks a lot !!

P.S. amelia watson's character mod from ZeroRyuk : https://steamcommunity.com/sharedfiles/filedetails/?id=2411450759   (the mod I make reference to)
