MS Sql Dev Studio & EditPlus...

I've configured external tools to include my favorite editors -- when I want to look at a 'collapsible' version of the script I launch EditPlus. Then I can expand all/collapse all (or portions) of the script for easier review/managment. For really long SQL scripts -- I've found this invaluable. If there is a 'code folding' option within MS SQL Server Mgmt Studio -- I have yet to find it.
