It may be possible to configure other variables in the InterMap 
definition, but it would not be practical to change the variables to 
different values in a page.

A markup expression for a Text Fragment may be easiest to define and use 
in a page:

   [[DeWiki:Hamburg{(txfrag "Stauwerk Geesthacht")} | click here]]

Here is a function that implements most of the standard from:
   
https://developer.mozilla.org/en-US/docs/Web/URI/Reference/Fragment/Text_fragments

   $MarkupExpr['txfrag'] = 'ME_TextFragment($args)';
   function ME_TextFragment($args) {
     foreach($args as $search) {
       $encoded = implode(",", array_map("rawurlencode", explode(",", 
$search)));
       $out[] = "text=$encoded";
     }
     return "#:~:" . implode('&', $out);
   }


In the page, use this:

   {(txfrag "Highlight this text in the page")}
   {(txfrag "Start text,End text")} highlight between 2 texts
   {(txfrag "Term 1" "Other Term")} highlight separate terms
   {(txfrag "prefix-,term to find,-suffix")} see reference

Use quotes if you have spaces in the search terms.

It should also work with other URLs, not InterMap.
