Here's a cool little Android "L" feature you may not have noticed - just bring up your lockscreen and swipe right. Boom. Dialer. This new shortcut, unlike the old camera gesture, does require that you enter your pin or unlock code before the dialer will actually open, but it's handy nonetheless.

You can, of course, alternatively swipe up on the dialer icon at the bottom of the lockscreen, too, though this is arguably quicker and definitely a bit more eyes-free in terms of getting the gesture right.
