   1 <p>This tests moveTo{Beginning, End}OfLineAndModifySelection.  It should operate on line boundaries and not paragraph boundaries.  To run it manually, click inside the first line of the editable region below and do Command+Shift+Left/Right Arrow, the selection should extend to the start/end of the line, not the start/end of the paragraph.  Also, moveTo{Beginning, End}OfParagraphAndModifySelection should work.</p>
   2 <div id="div" contenteditable="true" style="width: 200px;">The quick brown fox jumped over the lazy brown dog.</div>
