The Page Up and Page Down keys among other keys

The Page Up and Page Down keys (sometimes abbreviated as PgUp and PgDn) are two keys commonly found on computer keyboards.

The two keys are primarily used to scroll up or down in documents, but the scrolling distance varies between different applications. In cases when the document is shorter than one screenful, the Page Up and Page Down keys don't respond.

The arrow keys and the scroll wheel can also be used to scroll a document, although by smaller incremental distances.

In most operating systems, if the Page Up or Page Down key is pressed along with the shift key in editable text, all the text scrolled over will be highlighted.

In some applications, the Page Up and Page Down keys behave differently in Caret navigation (toggled with the F7 function key).

Microsoft patent

As of August 19, 2008, Microsoft has acquired a patent for making the Page Up and Page Down keys move exactly one page in a word processing environment, rather than the usual behaviour of moving up one screens' worth of text.^[1]
