What is "htaccess file support " ?

Hello,

I have been searching on the site about this but have not found anything specfic to this other than it is now supported in 2.0.1 PhpStorm.

Is this just the drop down hints / code completion for htaccess files?   I tried that and it works great but I wasn't sure if there was more to this "support" or if it was just the code completion.

Is there any documentation about this new feature?   I wasn't able to find a whole lot in the help doc or on the site about it.

Thanks.
