Quick answer
Officially listed controls
The official Roblox description lists Sprint: Shift, Scream: Q, Speak: T, Unlock Mouse: Z, and Emote: G. It also notes that console and mobile support are incomplete.
For Bahkruums controls, use the official Roblox listing as the current source of truth. Bunny hopping is also mentioned there; no more detailed platform mapping has been verified yet.
