# The page tree in the TYPO3 backend {#page-tree}

The **page tree** is a hierarchical structure that represents pages and their
subpages on a website, allowing editors and integrators to easily organize and
manage content and navigation.

It is displayed on the left of backend modules with
[navigationComponent](https://docs.typo3.org/permalink/t3coreapi:confval-backend-module-navigationcomponent@main)
set to `'@typo3/backend/tree/page-tree-element'`.

Usage of the page tree is described in
[Getting Started Tutorial, Page tree](https://docs.typo3.org/m/typo3/tutorial-getting-started/main/en-us/Concepts/Backend/GeneralBackendStructure/PageTree/Index.html#page-tree).

The page tree can also be navigated via [Keyboard commands (Tutorial for Editors)](https://docs.typo3.org/m/typo3/tutorial-editors/main/en-us/HelpInside/KeyboardCommands/Index.html#keyboard-commands).
