We've all been there. Things are slow at work and you find yourself somewhere you shouldn't be, like playing a game of online Scrabble or watching some painfully awful rendition of the national anthem on YouTube. Without warning, here comes the boss and he or she seems to be approaching at the speed of light. In a state of panic, you fumble with your mouse and keyboard in an attempt to close your browser before its too late. No such luck, as the six deadly words fill the air in your cubicle: "What is that on your screen?".

Don't let this happen to you! These shortcuts can help you hide or shut down your browser lickety-split. Just be sure that you do not have any important work open in your browser if you intend to quit the application.
Please note that on Macintosh (OS X), using Hide is noticeably faster than using Quit.
