This is a little OT, but if anyone is interested:

• Brief: Set cursor inside input element throug row and column
• Dependency: setSelectionRange() from @ashkan nasirzadeh

• Example call: setTextCursor(textarea,textarea.val, 0, 1);

  // @brief: set cursor inside _input_ at position (column,row)
  // @input: input DOM element. E.g. a textarea
  // @content: textual content inside the DOM element
  // @param row: starts a 0
  // @param column: starts at 0    
  function setTextCursor(input, content, row, column){
    // search row times: 
    var pos = 0;
    var prevPos = 0;
    for( var i = 0; (i lineEndPos-pos)){
        // go *only* to the end of the current line
        pos = lineEndPos;
    } else{
        // act as usual
        pos += column
    }
  
    setSelectionRange(input, pos,pos);
  }
