Can I lock my screen with a keyboard shortcut? Possible Duplicate:
  Is there a quick way to lock my Mac?  




I'm running OS X 10.7.3

Currently I've found what looks like 2 possible solutions:


Hot corner(s) setup in the "Desktop &amp; Screen Savers" preferences
Create a service with Automator then map a keyboard shortcut in "Keyboard" preferences


I don't like 1 because it requires the mouse, and 2 seems like a bit of a hack. Is there a built in way to do this? Or should I settle for the workarounds?

Thanks

Does control+shift+eject  (    sleep displays ) solve your problem?    (if you set authentication for login)   

Or you can use Option+Command+eject    Put the computer to sleep.
