Switch between computer mode & monitor mode

I connect my MacBook Air with my iMac using a mini DisplayPort cable at home. How can I switch the monitor mode of iMac to pc mode and vice versa without unplugging the cable. Thanks!

How to use target display mode

  1. Make sure that your iMac is started up and meets the system requirements above.
  2. Make sure that the other Mac is started up and logged in to a macOS user account. 
  3. Connect the two computers using the appropriate Mini DisplayPort or Thunderbolt cable. 
  4. You can use more than one iMac as a display, if each iMac is using a Thunderbolt cable to connect directly to a Thunderbolt port on the other Mac (not the other iMac). 
  5. Press Command-F2 on the keyboard of the iMac. You should now see the desktop of the other Mac.
  6. To exit target display mode, press Command-F2 again. Or disconnect the cable, or restart either Mac.
