This Tip is Useful for resuming work on a document we have been working before.
In a Microsoft word document, pressing CTRL+ALT+Z will take you back to the last place edited. It’s a great feature if you write in an iterative way (i.e. write different parts of the documents simultaneously). It is also useful when you write or review a document and want to see where you stopped the last time.
This works for just after opening a saved document.
