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). For a claimed 30% of people, the Page Up and Page Down keys move the text in the opposite direction to what they find natural,[1] and software may contain settings to reverse the operation of these keys to accommodate that (the origin of the 30% is unknown).
