In the Editor toolbar, just click the second button to access your previously saved documents.
WordHero has an autosave feature, so any changes you make to your document will be saved.
If you accidentally deleted a sentence, paragraph, or the entire content of your document, just undo the action immediately by pressing CTRL+Z on Windows and CMD+Z on Mac.
If you have further questions, contact support@wordhero.com, and we will be happy to help you.
