One of the best features of ExpressScribe is "Play With Pausing" functionality. You can can configure your hot-keys so that the audio plays then pauses (with a bit of rewind) so that you can catch up to the recording while typing.
This eliminates the need for a foot pedal. After using this, I would never go back to a foot pedal.
I have my F11 key configured so that when I start an audio file by pressing F11, it plays and pauses, thus eliminating the need to rewind the audio.
