An editing method includes: detecting a selection of first and second clip portions of a source media depiction, generating corresponding first and second block icons and snapping hands-free the first and second block icons across the screen to a linear queue so that the blocks are snugly adjacent, detecting a move of the first or second block icon relative to one another substantially along the queue, and if the first or second block icon overlaps the other by substantially one half of the other block icon, reversing displayed positions in the queue of the first and second block icons.
