Thank you for your reply Steve! The reason I started typing into the application is because transcription goes much faster as you can use the hot keys. I found that when I typed into Word outside of the app, while listening to the audio on the app, I wasted a lot of precious time going back and forth between apps because I had to use the mouse constantly to stop and play etc, and the hot keys (shortcuts) didn't work. However, now, that I recovered my work (Command Z saved me! Thanks Internet!), I will be saving my work as I go along.
