In-Cockpit View while not in IVA

I see many users have taken photos with new parts and they have a transparent canopy that shows the interior view of the command pod through the windows. What do you do to enable this setting?

Hover your mouse over the Kerbal portraits and click on the little button bottom left of the portraits. There might be a key mapping that I'm not aware of though.
