  Is there a quick way to lock my Mac?  




whenever i used to leave my system i just press WINDOWS+L in my windows system. Now i have macbook pro with snow leopard OS and i am searching for equivalent of windows+l.

So my question is what is the keyboard shortcut to lock macbook pro? 

i know the shortcut COMMAND+SHIFT+Q.
But this shortcut is for logout not to lock the system.
control+shift+eject sets the display to sleep. If you have then the option "Require password immediately after sleep or screen saver begins" set in "Security &amp; Privacy" it will lock your machine.

This will only put the display to sleep not the system: not exactly what you asked but the additional screen sleep is not bad (less energy consumption :-)

There are other answers here that point out ways to establish a automation to lock the screen from a keyboard command of your choosing. See

The last two show several methods to script this. You can then use LaunchBar or FastScripts or another tool to launch the action you prefer.
