Use F12 as "Insert" in macOS terminal

On Apple keyboards we don't have an Insert key, and this is most annoying when using the command line or CLI tools like Midnight Commander.

We can fix this by re-assigning the F12 key:

  • Remove F12 as key from System Settings->Mission Control
  • Enable Use F1, F2, etc. keys as standard function keys in System Settings->Keyboard->Keyboard
  • Go to Terminal->Preferences and set the default profile as Pro
  • Go to Terminal->Preferences->Profiles->Keyboard and Replace F12 code with \033[2~
