I don't see a "Show in Sidebar" command in the View menu. Perhaps you mean "Go to Sidebar"? That just changes the keyboard focus so you can navigate the sidebar outline or the main outline without mousing.

Can you post a screen shot of what you are seeing? Do you have the sidebar collapsed? That is, do you see a ~6 pixels wide bar on the left edge of the window with a small dot in the middle of it? Collapsed sidebars are a standard Mac interface feature. Just drag the bar to the right to reveal the panel.
