TYPO3 v8 has reached its end-of-life March 31st, 2020 and is not maintained by the community anymore. Looking for a stable version? Use the version switch on the top left.
You can order Extended Long Term Support (ELTS) here: TYPO3 ELTS.
The Top Bar¶
The top bar contains some information and additional menus.
To the left is the TYPO3 CMS logo (which can be modified by an extension, as the Introduction Package does), then comes the name of your site (this is part of global configuration, which is decribed later).
The star icon will open a list of bookmarked views. Every time you see such an icon in the TYPO3 CMS backend, you can click on it and the current view will get saved to this list of bookmarks.
The lightning bolt icon opens the menu to flush the various caches that are used by TYPO3 CMS to improve performance. Caches are described in detail in Core APIs.
The question mark icon opens the help menu, which gives access to various modules related to help and documentation.
The next icon opens up a panel showing various information about the current system and TYPO3 CMS installation.
The user name is displayed next. It opens a menu giving access to the "User Settings" module, where you can change your password and various preferences. Here is also the "Logout" button.
Finally, flush right, is a general "Search" field, which will search through all records (pages, content elements, users, etc.) existing in the current TYPO3 CMS installation.
