The Inspector - missing button(s)?

[niassa]

I’m not sure if this is a bug or if I’m just missing something.

I’m finally having a chance to go through the tutorial and I’m on Step 5. It says:

Right, let’s look at the inspector. Right at the bottom of the inspector, in the footer bar, you will see four buttons and a padlock icon.

The padlock button on the far right allows you to “lock” the inspector to a particular editor when the editor is split - we won’t worry about that for now, though, as we haven’t looked at splitting the editor yet. The other buttons allow you to choose what to view in the inspector, and how many buttons appear will depend on what you are viewing in the current editor. The last button, “Snapshots” (the one with the camera), is only available for text documents, for instance.

I see a Notes icon (piece of paper), a Reference icon (books line up with one leaning?), a Keywords icon (a key), and what looks like a padlock, especially when combined with the information above saying that the far right icon is a padlock. I click on it, however, and find that it isn’t the padlock icon, apparently, it’s the camera icon for Snapshots. Upon really close inspection of what I thought was the padlock button, I can maybe see that it’s a camera. I have no padlock button. Am I just missing something?
