Newbie --> Does anyone know what kind of key the bold code below creates?

[googsnet]

I need to know what kind of Key is generated by this PHP code (line 9)

1. <?PHP
2.
3. $query = "CREATE TABLE carttemp(
4. hidden INT(10) NOT NULL AUTO_INCREMENT,
5. sess CHAR(50) NOT NULL,
6. prodnum CHAR(5) NOT NULL,
7. quan INT(3) NOT NULL,
8. PRIMARY KEY (hidden),
9. [b]KEY(sess))";[/b]
10.
11. ?>

And is there a way to accomplish this through the phpmyadmin console that my hosting providers are forcing me to use?

Thanks in advance.

The manual:

KEY is normally a synonym for INDEX.
