Page Up and Page Down keys
Page Up and Page Down keys (PgUp and PgDn) are on most keyboards and are used to scroll a document up or down. How far they scroll depends on the program: some jump a whole page, or move by the current screen view depending on zoom. If the document fits on the screen, the keys may do nothing.
Different operating systems handle them differently: sometimes they move only the view, other times they move the text caret too. In right-to-left layouts, PgUp may move up or right, and PgDn may move down or left. The arrow keys and the scroll wheel can also scroll, usually in smaller steps. With modifier keys like Alt or Ctrl, they can behave like Page keys.
If you press Shift with Page Up or Page Down in editable text, the text you scroll over becomes highlighted. In some apps, the keys work differently for caret navigation (sometimes adjustable via features like F7 in Windows).
Some people find the keys move in the opposite direction from what they expect, and software can let you reverse this behavior. Microsoft received a patent for the Page Up/Page Down functions in 2008.
