PHP function suggest?

Hello!

I am wondering if PHPStorm will suggest PHP functions?  For example, if I type "str" will it immediately drop down a list of all PHP functions that start with "str"?  The Eclipse and Aptana editors used to and I really miss it... My current install of PHPStorm 95.192 isn't doing this.  If it has the ability to, can someone point me to the correct settings?
