Taking a screenshot, also known as a screen capture, enables you to save everything that appears on your screen as an image. It is a way to keep a record of how a website looked at a certain time and it’s also very handy during troubleshooting as it lets you show error messages to people using other computers. Macs let you take three types of screenshot, depending on how much information you want to capture.
Close down any windows or web browsers you don’t wish to appear in the screenshot by clicking the X icon. This is handy if you want an image you can show to anyone, without embarrassment. For example, if you need to send an error message screenshot to your IT department, close down Facebook before you do so.
Hit Command, Shift and 3 at the same time. You’ll hear the sound of a camera shutter clicking. This means that the screenshot has been successful. If you want to copy the image to your clipboard, rather than save it to your desktop, hit Control, command, shift and 3. This enables you to paste the image into a document or email.
Go to your desktop. You’ll see the screenshot saved there as a jpeg image. You can now move this to a suitable folder or if you’d prefer, you can leave it on the desktop. Once you’ve sent it, you may want to move it to trash. Do this by dragging it to the trash icon.
Hit Command, Shift and 4. This opens up a crosshair control.
Use the crosshairs to highlight the part of your screen you wish to capture.
Let go of the mouse or trackpad to take the screenshot.
Hit Command, Shift and 4 as though you were going to take a crosshair screenshot. Hit the spacebar. This brings up a camera icon.
Move the camera icon around your screen. The camera icon enables you to take a dynamic screenshot, as it interacts with your Mac in the same way the cursor does. You can open the doc or the file menu before taking your snap.
Release the mouse or remove your finger from the trackpad to capture the screenshot.
