title: avoid ie contentEditable element to create paragraphs on Enter key
body: <p>On InternetExplorer, a contentEditable DIV creates a new paragraph (<code>&lt;p&gt;&lt;/p&gt;</code>) each time you press Enter whereas Firefox creates a <code>&lt;br/&gt;</code> tag.
  Is it possible to force IE to insert a <code>&lt;br/&gt;</code> instead of a new paragraph ?</p>
