I've been changing shortcuts ever since I got my new macbook so that I can retain my muscle memory from window PC. I've managed to customize lots of shortcuts for chrome via system preference, as long as those shortcuts have a corresponding menu title in chrome. However, to open a new tab in background, the shortcut in PC is ctrl + click, while this in mac is command + click. How to change this?
I don't think you can do this easily just for Chrome. Your best bet to actually change the keys will be to globally swap your command and control keys in System Preferences:
I agree with @Tetsujin 's comment that it's easier just to get used to the paradigm shift in the long run. The Apple keyboard is laid out slightly differently, and it feels weird (to me) trying to use Windows key combinations on it.
