Question

I use PhpStorm to edit PHP files and configuration files for Apache. How to comment on the selected block and set the symbol comment?
I want,for example,

   <Directory />
        Options FollowSymLinks
        AllowOverride None
        Order deny,allow
        Deny from all
    </Directory>

to

   #<Directory />
   #    Options FollowSymLinks
   #    AllowOverride None
   #    Order deny,allow
   #    Deny from all
   #</Directory>

Select multiple lines and use the Comment with Line Comment (Ctrl+/ in the default keymap on Windows, can be changed in Settings | Keymap).

There is also Comment with Block Comment that works for file types that have special style comment for code blocks (not applicable for .htaccess).
