Binding the Tab-Key to "self_insert_cmd" would result in the expected
behaviour. (But not in the one of Visual Studio...)

Do you mean, Tab inserts a tab character (or TAB spaces) in every line of
the region at the current column position and Shift-Tab backward-deletes TAB
spaces...?

2 ways: 
 
  * personally, I use the versatile rectangle functions quite heavily:
    In my extended cua.sl you find the bindings
    % ^R: rectangles
    ...
    setkey ("kill_rect",   "^RX");          % delete and copy to rect-buffer
    setkey ("open_rect",   "^R ");          % ^R Space: insert whitespace

    To indent a region by a fixed amount, I mark a rectangle (mark at
    current start of region-text, spot at last line of the region and at the
    column the region shall start after the indent) and press ^R Space.
    
    To dedent a region by a fixed amount, I mark the rectangle to be deleted
    and press ^R X. 
    
    -> Fast, versatile (I can easily determine the number of spaces to
    insert/delete) and efficient.

  * Another option would be to define a function that inserts a tab (or TAB
    spaces) in every line of the region (or just the current line, if no
    region is defined) and bind it to the indent_line_hook (if you want the
    indent_to_the_right_level feature in programming language modes) or the
    Tab-Key (if you want the indent-by-fixed-amount feature in all modes).
    
    % Insert TAB spaces in all lines of the region (or the current line, if
    % no region is defined)
    define tab_region_or_line()
    {
       !if(markp)
       {
          bol();
          push_mark_eol();
       }
       narrow;
       variable col = what_column();
       bob();
       while (down_1)
         {
            goto_column(col);
            insert_spaces(TAB);
         }
       widen;
    }
