Keyboard shortcut for display sleep on MacBook Air?

The Air has no Eject key, so the Ctrl-Shift-Eject doesn't work. What's the replacement key?

Thanks

 

Lock Screen

What's Apple's official/prescribed method to lock the screen? It would seem those steps all involve 'workarounds' or third party solutions.

Thanks

 

The problem with mixing Screen lock functionality with Display sleep is compromise on power savings on notebooks.

For example, on other OSes, I have it so that after 1 min on inactivity, it turns the screen off but immediately turns it back on as soon as I touch the trackpad.

This doesn't seem to be possible on the Mac because it would prompt for password every time I look away for a minute or 2 to speak to someone or refer to something.

Now if I disable the password prompting, then there is no way to lock the screen now. So I was just curious if Apple has a 'recommended' workflow for how they think you should be locking your screen.

 

But since the Display Sleep and Computer sleep password prompting is tied together (in addition to the lock/sleep coupling), doing so will mean that when I close the lid of my notebook, anyone can open and get right in.

It will disable the resume from sleep prompt as well.
