+Examples:

+- /mapmap/paint/opacity ,sf movie.mov 0.1   Change opacity of paint named "movie.mov" to 0.1 (10%)
+- /mapmap/paint/opacity ,sf "movie_*" 0.5   Change opacity of all paints whose name begins by "movie_" to 0.5 (50%)
+- /mapmap/paint/rewind ,s "*.mov"           Rewind all .mov paints
+- /mapmap/mapping/solo ,s "mesh_[0-9]" 1    Sets all mappings that begin with "mesh_" followed by a single digit to solo mode

+## Playback
