Again, this is another common feature of Word that everyone knows – but be aware there are a few different ways to use it, with some powerful traits! It is found under the Edit menu, though most people I know use the toolbar button (a bent left arrow). This will undo a single action – though the shortcut "CTRL+Z" achieves the same thing, without pausing your typing. But many people do not realize that you use "Undo" to reverse multiple actions at once, or choose a specific previous action to undo!
On the toolbar, there is a "look in" arrow to the right of the Undo button. (A black triangle pointing down.) Click it to open, and then slide your mouse down the list. This list will highlight, and clicking the bar at the bottom of the list (which reads "undo x actions" depending how many you've highlighted) will undo the listed number of actions, at once! Right now, I could undo 216 actions – which would take me back to the title of this article!
This is a powerful feature that can save lots of time, since in editing an article, you can often backtrack to a place you chose the wrong path! You can also use it to find a specific action you performed earlier, and undo that single item. Or, for example, you can wipe out a group of edits you made that you decided you really didn't like, while keeping all the more recent changes you did like!
