The list of shell-scripts is customizable at run-time. Alternatively, the program option "-customizeAddScriptByRegex" can be used to specify a file with shell-scripts. Example: 
   demo\Example google%09.*%09http://www.google.com/search?q=*
   demo\Example: Matches starting with M%09^M.*$%09 echo starts with letter M *
Each line associates a shell script (3rd column) to regular expression (2nd column). The asterisk is replaced by the text. The shell script is presented to the user as a menu item. The menu item path is given in the 1st column with back-slash being the separator. If the value in the 3rd column starts with http://, then it is not taken as a shell script but as a Web address.
