Skip Length Designed to speed up navigation and prevent unintentional track skipping when listening to long audio tracks, SKIP LENGTH changes the behavior of the Prev and Next buttons so that they skip by a given number of minutes instead of skipping to a new track. Note: To skip tracks with this setting set to a time interval, press Short Prev + b Long Next to go forward and Short Next + Long Prev to go back.
