Step by Step, How To Set Up Whisper Keys Mumble v1.2.15 On the top navigation bar click SETTINGS > SHORTCUTS Here you can see my PUSH TO TALK is already set to CAPS LOCK. We are going to add a new keybind. CLICK ADD Click where it says UNASSIGNED and set up your new shortcut for WHISPER/SHOUT After setting it to WHISPER/SHOUT click DATA This opens up a new smaller dialogue box To add people to your Whisper Chat select Users from the drop down list. You can ONLY select users who are CURRENTLY ONLINE and REGISTERED. You can also set up a key to shout to an entire channel ^ Set your keybind/shortcut. Here I used the '+' key. Click APPLY and you're done. Regular Push to Talk gives you Red Lips Whisper Chat will show you Blue Lips This is a helpful function for officer teams, large scale PvP with shotcallers in separate channels who need to relay messages, even groups of friends who are playing separate games and in different channels I suppose. In order for this to be set up as a private Officer Whisper Channel EVERYONE will need to set this up individually. For the example pictured, Overzealous would need to have Paradigm, LoanWolf and I added to a shortcut. Loan would need Over, Paradigm and Me added to a shortcut, etc etc. Also, even if someone is in the AFK channel it will still Whisper them, even if the receiving user is suppressed. Just something to keep in mind. Also, if you set up a whisper chat with a group of people it'd be proper etiquette to begin your statement with 'Whisper Chat' or 'Officer Chat' so the other people know you are not talking in the main channel. So they know what key to hit to respond to you.
