1. Enable the hidden text
b. Select Display, then Make sure Hidden Text is selected:
2. On the ribbon, in the editing box (typically far right), select the select drop down, then Select Text with Similar Formatting.
3. On the ribbon in the styles box click the arrow with the bar above it
and select clear formatting
There you go, now you know how to clear the formatting, there are some other ways floating around the internet explaining how to make hidden text normal text, but they didn't work for me. This worked.
Good luck and let me know if you find any other solutions that are easier (short cut keys would be awesome too).
