@ -222,6 +222,9 @@ radio_step_channel <-1|1>
Step forwards (1) or backwards (-1) in channel list. Works only when the
'channels' radio parameter was set.
radio_step_freq <value>
Tune frequency by the <value> (positive - up, negative - down).
seek <value> [type]
Seek to some place in the movie.
0 is a relative seek of +/- <value> seconds (default).
