1. Open Microsoft Word.
2. Toggle browse mode.
3. Open the Elements List.
4. Press Alt+E to get the spelling errors.
5. You will be placed in the Filter by field.
6. Press it again, you're stuck.

I propose that Alt+S or Alt+R be used instead to move quickly to the errors. Alt+S would be ideal, since these are spelling errors. However, Alt+R is also available, so it can be used.
