Multiple Undo and Redo Steps in MS Word

In MS Word, you can not only do multiple undos but actually select a bunch of them and do it all together in one click! Redo just repeats the last step.

As you type and format text, Word keeps a record of all the major changes and lists them in the Undo drop-down list:

You can select as many undo steps as you like by scrolling the cursor over the list. Those selected undo steps turn yellow.  When you click on the last undo step selected, the Word revert backs to the last step taken BEFORE the last deleted step.

Redo, on the other hand, restores one step at a time, starting with the last one.
