Delete or Backspace removes the selected picture as one undo step. Left and Right leave it for
the end of the text outline before it in page order or the start of the one after, as OneNote
2010 does; OneNote has no arrow nudge for pictures. Its Up and Down wrap the picture into a
new outline with a caption below, which needs pictures inside outlines and is not modelled.
