Hello there, i'm new to modding and am trying to implement custom keybinds for an item but i cant seem to figure out how to set a keybind to 2 keys.

For context i have a key to lock and another to unlock, and i wanted it to be by default "left-click" and "shift + left click" respectively. I've been searching and can't find anything saying what i can and can't, only thing that keeps telling me its impossible to do this are AI's, but im pretty sure in modpacks i have played i could set other mods keybinds to 2 keys.

If someone could explain this to me or help it would be appreciated, thanks!
