Introduction
============

phpMyAdmin is a free software tool written in PHP that is intended to handle the
administration of a MySQL or MariaDB database server. You can use phpMyAdmin to
perform most administration tasks, including creating a database, running queries,
and adding user accounts.

Shortcut keys
-------------

Currently phpMyAdmin supports following shortcuts:

* k - Toggle console
* h - Go to home page
* s - Open settings
* d + s - Go to database structure (Provided you are in database related page)
* d + f - Search database (Provided you are in database related page)
* t + s - Go to table structure (Provided you are in table related page)
* t + f - Search table (Provided you are in table related page)
* backspace - Takes you to older page.

A word about users
------------------

Many people have difficulty understanding the concept of user
management with regards to phpMyAdmin. When a user logs in to
phpMyAdmin, that username and password are passed directly to MySQL.
phpMyAdmin does no account management on its own (other than allowing
one to manipulate the MySQL user account information); all users must
be valid MySQL users.

.. [#f1]

    phpMyAdmin can compress (:term:`ZIP`, :term:`GZip` or :term:`RFC 1952`
    formats) dumps and :term:`CSV` exports if you use PHP with
    :term:`Zlib` support (``--with-zlib``).
    Proper support may also need changes in :file:`php.ini`.
