Microsoft office tip:

Renaming or Deleting Files when Saving or Opening

You can rename and delete files any time you are using a FILE > OPEN or a FILE > SAVE dialog box.
When you see the list of files when browsing in the current folder, you can treat is just like the windows explorer window, by selecting and then editing.

To rename, just give the file a single click to select, then a second to enter the file name. Type the name you want, and press enter.

To delete, a single click and hit the delete key.
