TYPO3 provides a huge service offer

Below is an extensive list of the features TYPO3 has to offer. Some features are built into the system core (Core), while others can be added by installing third-party extensions (Ext) that are freely available in the TYPO3 extension repository (TER).

Functions for Content Editors

These functions aim directly at editors who have to take care of the content of one or several websites.

Function	T3 Core	Ext	Details
Rich Text Editor (RTE)	X		Multiple RTEs with Microsoft Word-like icons, support for Win/IE, Mac/Safari and Mozilla Firefox on all platforms; WYSIWYG editors are highly configurable -- buttons and CSS styles can be added and removed.
Intuitive User Interface (UI)	X		The site is organized and displayed in the backend in a page-tree format that duplicates the structural layout of the site. File management functions are displayed in a directory-tree format that duplicates the directory structure of the installation. This makes finding pages and files easy for content editors.
Spell Checker		X	Is built into the RTE.
Configurable UI Levels	X	X	Customizable/Skinnable backend interface for editors (expert or newbie interfaces); Help icons are located beside most functions.
Unlimited Undo-Function and History	X		TYPO3 has unlimited history. You can undo any change you make on the site.

Frontend or Backend Editing	X		Users can choose to edit in either the frontend (directly on the webpage) or the TYPO3 backend.
Preview Content	X		Hidden, time- or access restricted content can be previewed online before publishing.
Multiple Page Editing			Any level of pages can be loaded into an editing form by specifying parameters such as name, date online/offline, etc. to be edited at the same time.
Shortcuts	X	X	Repetitive operations and frequently used internal modules can be captured as a shortcut in a single click. Having a collection of shortcuts, users can jump around inside TYPO3 with little effort. Shortcuts can be grouped, named and even added to user groups by administrators.
Wizards	X		Content wizards exist for forms, tables and image manipulation.
Task Center		X	Ability to create and manage projects, email project members, edit recent pages, view/manage inbox, insert notes onto webpages and create special actions for downloading CSVs of parts of the database or setting up backend users quickly.
Internal Search Engine	X	X	Editors can perform a search for a keyphrase within a section of the site. The results will return all the content elements with the phrase included. These can be edited at the same time. An extension performs a similar function, but allows the string to be replaced.
