J or I key numbers for LUA?

I cannot find I or J for example under the [ Controls - Cfx.re Docs ]

That being said, how could someone use I or J as keybinds using
IsControlJustPressed(0, ?)

Or is it not possible with FiveM?

Keys don’t have ‘numbers’, and you can’t get keys directly at all.

If you want to use keys that aren’t bound to an action by default, use key mappings, but note that users can change the keys bound to such actions themselves.
