Every modern day smartphone should have the ability to take screen shots and it is nice to see that the BlackBerry added this feature to the BlackBerry Z10.
To take screenshots, all you have to do is press and hold the Volume Up and Volume Down button at the same time. If done properly, you will hear the normal camera click sound, see the screen flash, and, a 1280×768 .png image will be created.
If you go into your Pictures application, you will see all your screenshots which can then be edited or shared as you see fit. As a final note, the current rotation of the screen can affect the screen shot, therefore if you want the image to be in landscape make sure you rotate your BlackBerry Z10 accordingly.
