PC keyboard on Mac

[rich1812]

Hello, recently my mac wireless keyboard died. I replaced it with a PC keyboard. most keys work just fine except one. On the Mac, I could press command+shift+poer 9or eject) to shut off the screen without putting the Mac to sleep. But on the PC keyboard, it has neither power nor eject key. The is the feature I miss the most about Mac keyboard. How can I map one of the keys on the PC keyboard to response to eject or power? Thanks. System preference doesn't help.

There is a shortcuts section in settings. If it is listed there, you can redefine it. If not, I'm not sure if it can be done without modifying the system.
