This is why I love macOS so much! With the command key, there is no overlap for things like copy and paste and ctrl + c/v. Also Cocoa implements things like ctrl + a/e etc for every native textfield and textview, so I‘ve gotten really used to it.

Too bad now I‘m mostly on Windows and miss all these shortcuts. In programs where I can edit the keymapping, I usually change ctrl + a from Select All to jump to beginning of line. I barely use Select All anyway.
