Search Mode can be set to

   EXACT       : a search-string must be identical to a string in the
                 buffer for a match to occur.
   APPROXIMATE : 1) lower case characters will match capitals also, and
                    vice versa;
                 2) modified characters will match non-modified characters
                    also, and vice versa.

   DEFAULT     : APPROXIMATE
                 TVini may overrule this.
