I have my security preferences set up to delay for 15 minutes after screen saver turns on and then ask for a password. (I use two computers and don't always notice right away when the screensaver turns on on my mac.)
However, when I walk away from my mac, I would like to be able to hit a keyboard shortcut or use hot corners to require a password right away.
I've tried using ctrl-shift-power, but that simply turns the screen off while not requiring the password. Hot corners would be ideal if that's possible.
Is there a way to do this?
