For as long as I can remember I have been frustrated by the browser behavior whereby using the
Page Up and
Page Down keys on the keyboard doesn't scroll the web page by a full screenful. Whenever I am reading a long web page, I prefer to read the whole screen from top to bottom, press
Page Down, then continue reading at the top of the next page. However, doing this always leaves a few lines of the previous screen at the top of the next screen. Often this completely breaks my concentration as I search through the first few lines of the screen to remember exactly which line I previously left off reading on the previous screen. Simply rereading the first few lines again each time has a similar effect on my concentration.
Is there any way to change this behavior so that the
Page Up and
Page Down keys scroll 100% of the current screen instead of leaving a few lines of the previous page at the top of the screen after a "full page" scroll? This "partial page scrolling" behavior seems to be the normal behavior on current versions of IE, Chrome, Firefox, and Safari, though by differing amounts (IE and Chrome both leave about five lines from the previous screen, while Firefox and Safari only leave one or two).
For example, here is a screen in IE9 before using the
Page Down key:
And here is the next screenful after using the
Page Down key (the "duplicated" lines are circled in red):
