Take Screenshot Without any app

If you already know this technique then this post is not for you,but if you dont know any means of taken screenshot on your device other than using some applications,then this is for you.
Taken screenshot on most android device have been with the aid of third party applications some of which require root access especially low end devices, and as a result a lot of people root their device solely for this.Should i say people neglected the inbuilt capability of android low end devices to take screenshot or just prefer third party apps to do it for them? In my opinion i will choose to say, this feature is to some extent an hidden or not too popular.To take screenshots on your device without  root access or the help of application all you need to do is:
*Press and hold the home key for 1secs and immediately press the power button,then your  current page will be snapped.
*You can find your screenshot in sdcard/ScreenCapture

Note:
You have to press the home button for atmost 1sec(before task manager comes up)then press the power button almost simultaneously.
If you use a galaxy pocket it works.
