While playing a video or audio file,
tap the player to create a loop.
A numbered button will be added to the loop collection.
Each loop has an end-time corresponding to the time when you tapped.
The first loop has a start-time of zero;
subsequent loops start where the previous loop ended.
Tap a button in the loop collection to activate its associated loop.
While a loop is playing, loops can be linked by tapping and holding a different loop.
Loops can be un-linked by tapping a different loop.
Play at regular-speed or half-speed.
