  Using Regular Expressions in Necromancer's Dos Navigator...
 
 
   When searching in Viewer and File Searching by contents, it's recommended
  to use '[^\n\r]' instead of '.' (w/o quotes), because, in these cases the
  file is being wholly processed. In Editor, you could use just '.'.
 
   Regular expressions are made up of symbols, described here:
    c            is symbol  (no case-sensivity), if it's not metasymbol.
    \c           is symbol, determined by escape-sequence,  the syntax of
                 which is the same as in string constants of C-language,
                 or the symbol  (no case-sensivity), in case, this symbol
                 is not an escape-sequence.
    .            is any symbol, including the end of line.
    ^            is the beginning of line.
    $            is the end of line.
    [c1c2c3...]  is any symbol from c1c2c3...
                 The range is created like c1-c2.
    [^c1c2c3...] is any symbol which not included in c1c2c3...
    
   Regular expressions are made up of another regular expressions, 
  by below-mentioned rules:
    r1r2     is r1 after which directly follows  r2 (concatenation).
    r1 | r2  is r1 or r2 (alternative).
    r*       is r, which repeaed 0 or more times.
    r+       is r, which repeated once or more times.
    r?       is r, which repeated 0 or 1 times.
    (r)      is r, which represents group.
  
  Lines replacing:
    $&       Replaces existing line.
    $n       Inserts text, from group number 'n'(0-9).  
  
  Special symbols:
    \a       0x07   BEL          
    \b       0x08   BS           
    \t       0x09   HT           
    \n       0x0A   LF           
    \v       0x0B   VT
    \f       0x0C   FF
    \r       0x0D   CR
    \xHH     2 he-symbols code
