My first try with Discord was pretty frustrating. I've done a lot of searching but can't find answers for some specific things I want to do. How can I do the following?

• Listen to one person ONLY. So everyone else is muted except the one person I want to listen to. I had to right-click and manually mute everyone except the one person I needed to hear. (Btw I unmuted them 5 minutes later and they didn't realize that they were muted! Oh kids!)

• Is there a keyboard shortcut for muting and unmuting a person?

I found sites that talk about "muting a server." But I want to still hear from a DM chat, and be able to easily mute and unmute individuals without having to right-click every individual.
