Hotkeys: Added ALT == Option key compatibility for mac

Thanks. Yeah idk, that's what they are called here. We use ! a lot for not but have tried to avoid the other ones. Don't ask me 🤷

Is this ready for merging, or do you want to test the other shortcuts as well?

;) Yea, I'm just a pseudo developer here. lol.

Found that the up and down keys also use alt. so added this to the pull request. Otherwise, all the other ones work. Great stuff as always @Jowan-Spooner . Appreciate you and @coppolaemilio @zaknafean @exelia-antonov and the rest of the community. Yep. this small contribution is ready to merge.
