Keyboard shortcut to open in tab?

I’m having a hard time reproducing the problem. Here’s what I’m doing:

  1. Create new document (with default “Welcome” text)
  2. Right click on “Welcome” in the sidebar and choose “Open in new Tab”
  3. Click in sidebar, switch between tabs… all seems well.

Can you try the above (1, 2) steps and then tell me the exact sequence that I need to do to reproduce the problem you see?
