Taking a screenshot

To take a screenshot of your entire screen on windows simply press the PrntScr button on your keyboard:

This will copy the image ready to be pasted into your preferred image editing software.

Alternatively you can take a screenshot of just one window. To do this, click on the window you would like to take a screenshot of (i.e the Command Prompt/Terminal window) and press Alt + PrntScr on your keyboard:

This will also copy the image. You will not receive any confirmation that the screenshot has been taken.

Mac OS X:
On a Mac the most flexible way of capturing portions of your screen is to use the cross-hair method. To do this press Command+Shift+4:

Your cursor will turn into a small cross-hair reticle.

Click and drag your cursor to highlight the area you’d like to take a picture of.  A rectangle should appear where you drag your cursor. If you need to adjust your windows, press esc to return to a regular cursor without taking a picture.

Let go of the mouse. You should hear a brief camera shutter noise if your computer’s sound is turned on. That signals that your screenshot has been taken. You can then find your new screenshot on your desktop It will be saved as a .png file named “screenshot” labeled with the date and time.  – Earlier versions of OS X will save it as “Picture #”—for example, if it’s the 5th screenshot on your desktop it will be labeled “Picture 5”.

The method for taking a screenshot on most Linux distributions is the same as on Windows. Simply press the PrntScr button on your keyboard and you will either be prompted to choose a location to save it, or it will be automatically saved. (Usually in the pictures folder or on the desktop).
