Extend Mac OS X's Screenshots

Mac OS X has a variety of built in screenshot methods. Here's a look at a few that offer more versatility than the basic full-screen capture (Command-Shift-3):

• Press Command-Shift-4 and you'll get a crosshair cursor with which you can drag to select and capture a certain area of the screen.

• Press Command-Shift-4-Space to select the entire window that the cursor is over, clicking on the window will then capture it. The resulting screenshot will even get a nice drop shadow.

• Hold down the Space bar after dragging out a selection window to move your selection rectangle around on the screen.

• Hold down Shift after dragging out a selection to constrain the selection in either horizontal or vertical orientation, depending on the direction of your drag.

• Hold down Option after dragging out a selection to expand the selection window around a center point.

iPhone Used to Eavesdrop on Nearby Keyboards

This research finding from Georgia Tech sounds like it comes from the plot of a high-tech thriller — a team has figured out how to listen in on what someone is typing on a nearby keyboard by using the accelerometer and gyroscope of an iPhone 4 to sense keyboard vibrations and decipher sentences with 80 percent accuracy. Although the actual risk of this happening is essentially non-existent, it’s yet another example of just how important it is that smartphone security be maintained by manufacturers and users alike.favicon follow link
