Shift + P is the usual shortcut for Roblox freecam on PC, but it only works in experiences that allow it, and bybat/BYBAT content on Roblox appears to mention the same keybind.

How to open it

  1. Join the game or open the experience.
  2. Press Shift + P on your keyboard.
  3. Use WASD to move, Q/E to go down or up, and your mouse to look around.
  4. Press Shift + P again to exit.

Important limits

  • It is mainly available in supported games or for developers with access.
  • Some guides note that it works best when Shift Lock is turned off.
  • If you are on mobile, the standard shortcut usually is not available.

BYBAT note

A Roblox BYBAT help post also lists Shift + P as the freecam toggle and mentions a camera button for disabling the UI.

TL;DR: press Shift + P to toggle freecam, then use WASD/Q/E to move the camera.
