Locomotion Charm

"Meanwhile, Ron was reading two years' worth of Charms notes with his fingers in his ears, his lips moving soundlessly; Seamus Finnigan was lying flat on his back on the floor, reciting the definition of a Substantive Charm while Dean checked it against The Standard Book of Spells, Grade 5; and Parvati and Lavender, who were practicing basic Locomotion Charms, were making their pencil-cases race each other around the edge of the table."
