title: LyX - breaking long formula lines
body: <p>How can I break long formulas in LyX into two (or more) lines? I know how to write several lines of equations in one "math box" but I'm looking for a solution to break lines even in the middle of a parenthesis. </p>
  
  <p>I'm using LyX 1.6.4 and currently, when the formula is too big, it doesn't do anything (it just doesn't print the last segment of it, which is "beyond" the page).</p>
  
  <p>Is this possible in LyX?</p>
