Cheat codes
If the possible values are listed in the "Values" field of the table, they must be appended to the "cheatcode" with an = sign. For example, if 1280x1024 was the desired value for the screen cheatcode, then you would type screen=1280x1024 into the grub boot prompt, or for language, lang=pt.
