What the sources establish
The supplied materials show MONOCHROME being played through the normal Roblox client, but they do not provide an official MONOCHROME-specific control chart. Begin with Roblox's current desktop or mobile controls, then watch the on-screen interaction prompts in your session.
Use the evidence carefully
Do not rely on a third-party key list as a universal answer. Platform, accessibility settings, and developer updates can change what is shown or available; verify each prompt in-game.
Source note
This guide is based on the supplied MONOCHROME research corpus and the live Roblox game description. Video material is used as a real gameplay reference; it is not presented as an official patch note.
