Formatting Query Results in Oracle SQL Developer

In Oracle SQL Developer you can use what looks like optimizer hints (without the plus sign...) and specify what kind of output you want to generate:

SELECT /*csv*/       * FROM scott.emp;
SELECT /*xml*/       * FROM scott.emp;
SELECT /*html*/      * FROM scott.emp;
SELECT /*delimited*/ * FROM scott.emp;
SELECT /*insert*/    * FROM scott.emp;
SELECT /*loader*/    * FROM scott.emp;
SELECT /*fixed*/     * FROM scott.emp;
SELECT /*text*/      * FROM scott.emp;

The one I like the most is the /*html*/ output with the nice search functionality.
