OS X: force quitting applications

I have a couple of Macs at work.  Funny,  I usually install VirtualBox and live in a Linux VM.  So on those occasions where I need to kill a rogue app in OS X, I get quite peeved when I can’t remember the “we do it differently” key stroke combinations.

Bring up menu:

Command+Option+Escape

From Dock:

Option+Right Click

From Apple Menu:

Shift+Click on Apple in menu

Activity Monitor:

Select app then Quit Process button

From terminal:

kill -9 [pid] or killall [process name]
