How to use ‘page up’ and ‘page down’ feature in Chromebook?

If you are trying to scroll through a webpage you might find it difficult to scroll up or down, fast, using the keyboard, unlike the traditional windows PC keyboards. This is because Chromebook keyboards don’t have any key named ‘page up ‘ or ‘page down’. However, by using the upward and downward direction showing keys you can scroll up and scroll down a page as in regular PCs.

So here is the solution. Although there is no fast scrolling button in the Chromebook keyboard, the similar type of feature can be enabled by pressing and holding the search key  and then pressing the upward or downward direction key depending on your intended direction of scroll.
