CPLine
From Speedsolving.com Wiki
CPLine is a substep of many CP First methods, this step is usually done intuitively by first building a 1x1x3 block on either side of the cube and then permute (without caring about the orientation) the remaining 6 corners. Normally after this step EO is performed to orient the edges. The whole cube is reduced to <R, U, M, E> moves after CPLine.
