Hello. I'm hoping someone will be able to help me out. I have to use WordPerfect 5.1 DOS for my job which means I use the function keys for that. I am going to order a foot pedal to use with express scribe because when I use the function keys right now they only run express scribe and not WP and I have to close Express scribe in order to use function keys in WP. When I get the foot pedal is there a way to turn off the function keys on express scribe so I will not have the interference? Thanks for your help in advance.
