I'm experienced with Windows, not so much with Mac. I find myself often renaming documents from within the Open and Save As dialog box windows. I hope the description below makes sense to explain what I mean.
If you look carefully you can see the picture below is of the Open dialog box of Microsft Word in Windows.
In the example above, assume I was going to open the document called The Leadership Factor, but before I did this I realized that the filename of the document above was wrong. So I can click on this document (see how its highlighted) and if I want I can now rename it so that it ends with '2017' instead of '2013'. After renaming it, I can then click on the document called The Leadership Factor to open it up.
Can I do the same thing in macOS?
