Shift-Click Maximize Button to Fill Screen
You know the red button on a window is close and the yellow one is minimize and the green one is maximize, right? Okay, so you also know that some apps (like Chrome and Word) don’t fill the entire screen when you click the maximize button. Sure that’s find most of the time, but sometimes you actually want the window to fill the screen. Next time you want the current window to fill the entire screen, just hold down the shift key when you click the button. Poof! Big window!
