Android/iOS: This function is not available for smartphones. For tablets, you can switch between documents within the program window.
If you have multiple documents open at the same time, you can switch to a specific document and thus make it the active document:
▪Ribbon interface: "Windows" icon
In the ribbon, you will find an icon called Windows  on the ribbon tab View. If you click on it, a list of all open documents appears. Click on the desired document. |
▪Classic menu interface: "Window" menu item
| For classic menus, you will find a list of all currently open documents in the Window menu. Select the entry for the document to which you want to switch. |
▪Toolbar interface (Android/iOS only): "Window" menu item
You will find a list of all currently open documents for tablets via the hamburger menu  in the Window menu. Select the entry for the document to which you want to switch. |
▪Mouse: Clicking on a document tab
| Above the document, you will find a bar with tabs for all currently open documents. Click on the tab for the document to which you want to switch. |
 |
▪Mouse: Clicking into the program window containing the document
| Of course, if you have documents open in multiple program windows (see previous section), you can also simply click into the program window with the desired document to make this document the active document. |
▪Keyboard: Ctrl+F6
| You can also use the keyboard to switch between the currently open documents: Ctrl+F6 switches to the next document and Ctrl+Shift+F6 switches to the previous one. |
| Mac: On a Mac, you have to use the key combinations Cmd+F6 or Cmd+Shift+F6 to switch between documents. |
