  1. Pick an open tab and drag it to where you want your second instance. 
  2. Use the split view icon on the right corner of an open tab. 
  3. Open a new document (on the homepage) into a new instance. Tap the downfacing arrow on the notebook > open it in a new window. 
  4. Pick up a document and drag it to the side. 
  5. Select a specific page to open from the document’s overview. In this window pick and drag the page you want in a new instance. 
  6. My least favourite option: drag the app from your dock.
