"Pass to me" voicelines don't exist. Don't complain about that. Not like you have a reason to. Press Z, X, or V to open voice commands. Then any number 1-8 to do a specific command. And yes, 'E' does call for medic.
IF THIS GETS POPULAR (which is like 4 views for me), I'LL ADD AUDIO! Class doesn't do anything for now, but you can press 1-9 after starting the project to select a class 1. Scout 2. Soldier 3. Pyro 4. Demoman 5. Heavy 6. Engineer 7. Medic 8. Sniper 9. Spy
