could the use of modification, alt, and/ or key combos to execute keys??

for example
instead of using the number keys for the hotbar we could use
ctrl + 1
lalt + 1
or some other key of our choosing + come other key of our choosing.

also if key binds exist that we do not want to use, could there be a feature to null them or make the key 0 rendering it without a key at all??

0 means no key, at least that's what Ive always used.

i know this may be a stretch to ask but its something i have wanted for some time now. if i knew java i would try to make this myself, but i use your mod in every self made and shared modpack i use.
