These commands can be entered using the console found in the pause menu. If you do not see the console there, make sure you have debug mode and experimental features enabled in the settings. The commands are case-sensitive, so make sure you type them in EXACTLY as they are shown here. However, these commands are only required if you're using version 1.0 or older. From version 1.1 onward, all these commands have been migrated to the settings menu.
