Adding documentation cells
Cells come in a number of different forms. This book doesn't use them all. However, knowing how to use the documentation cells can come in handy. Select the first cell (the one currently marked with a 2). Choose Insert ⇒ Insert Cell Above. You see a new cell added to the notebook. Note the drop-down list that currently has Code in it. This list allows you to choose the kind of cell to create. Select Markdown from the list and type # This is a level 1 heading. Click Run (which may seem like an extremely odd thing to do, but give it a try). You see the text change into a heading, as shown in Figure 4-17.
