How to use the new emotes?

[Sticks]

I see people saying things like "nice" or "oops" or playing a little animation but theres no keys in the input configuration to show how to do them. What buttons are the defaults?

Go into your keybindings and theres a new option called "pallette swap/express" bind it to whatever you want. In a match, hit the "express" key that you binded and press a direction for different emotes. I'm pretty sure that left is "nice", right is "wow", down is "bring it". Not sure what up is. If you just tap "express" with no directional input, your character will taunt.
