-- This is meant to get you to the "next sign" in the subtitle grid.
-- When mocha-tracking over 1000 lines, it can be a pain in the ass to find where the sign ends and another begins.
-- Select lines that belong to the current "sign", ie. different layers/masks/texts.
-- The script will search for the first line in the grid that doesn't match any of the selected ones with "text" or "style". (see options)
