Android/iOS: This function is not available for smartphones. For tablets, document tabs can be moved within the program window.
If you have multiple documents open, you can arrange them as follows:
▪The document tabs (the tabs in the bar above the document) can be moved within the bar and thus arranged in any order.
| You can even drag a document tab out of the program window with the mouse in order to have a separate program window for this document. |
| Alternatively, you can drag a document tab from one program window to another. The document will then be integrated into the tab bar of the other program window. |
▪If documents are open in different program windows, you can move the individual windows manually and resize them, of course – just as you can with all types of program windows.
▪If you choose the ribbon command View | Windows 
| View side by side (in the classic menus interface: Window > View side by side), you can display the current document side by side with another open document on the screen. If more than two documents are currently open, the program first asks which of them is to be used in the other window.
