What's the logic behind the naming schemes of these 3 keys and their associated key combination functions? Ex: Why Command-C to copy instead of Control-C or Option-C?
Command (⌘) is probably used to "command" the computer to do something, while "Control (⌃)" might be similar, but not the same.
You command the computer to copy and paste text or porn, but you don't really control it doing that, as not much control is needed during such simple tasks.
"Option/Alt (⌥)" is for having an alternative option?
