It doesn't seem to work with ExpressScribe. I have 30 years experience, specializing in the specialty I applied for. It is a timed test and it takes forever without a working foot pedal. On top of that, I could not read ExpressScribe's tiny font so I could not proof. Zoom feature on my PC didn't work in ES and I was not even considered to the job. Sad when you have to use ES as many very qualified people will fail.
