 * Values in the form's option elements should consist of    *
 * a target frame name followed by a colon and then a        *
 * fully-quallified URL.  For example, to redirect the       *
 * contents of the frame (or window) named 'main' to the     *
 * the www.inequality.org web site, form an option element   *
 * as follows:                                               *
 *                                                           *
 *   <option value="main:http://www.inequality.org">         *
 *                                                           *
 * To redirect out of a framed context, simply put nothing   *
 * before the first colon, thusly:                           *
 *                                                           *
 *   <option value=":http://www.inequality.org">             *
