Navigation keys are special keys on a computer keyboard that help users move around documents, web pages, or applications. Common navigation keys include the arrow keys, Home, End, Page Up, and Page Down. These keys allow users to quickly scroll through content or jump to specific locations without using a mouse. In addition to these keys, many keyboards also feature function keys that can assist with navigation in specific software. For example, pressing F1 often opens help menus, while Alt combined with other keys can help users switch between open applications.
