/**
 * Find_Next_Selected.bsh - A BeanShell macro for jEdit that 
 * finds next occurrence of the selected text. It's meant to replace
 * the regular Find Next providing additional functionality. Just
 * reassign your Find Next shortcut to this macro.
 * 
 * New in version 1.01:
 * 
 * - Special behavior when regular expressions enabled: if the current
 * selection matches your regexp search string, then it issues a
 * "find-next" action (so it won't disrupt ongoing regexp searches);
 * otherwise, the selected text becomes the new regexp search string;
 * if the new regexp search string is invalid, a regular search is
 * performed.
