Windows keyboard on mac, change combinations? I have my reasons why I use a Win keyboard on a Mac, I'm interested to know how can I change keyboard combinations like: change  Ctrl ⌃  vs.  Win  key, I want on Mac to have  Cmd ⌘  functionality on  Ctrl ⌃  key and  Ctrl ⌃  on  Win ... it is possible or does any software exist for that?
You can change Modifier Key Assignment from
System Prefs > Keyboard > Keyboard > Modifier Keys...
