Apple EarPods discoveries

I bought a new pair, looked at the tiny manual, and discovered two options for the remote and mic that I never knew about:

A short press followed by a long press of the center button: fast-forward.

Two short presses followed by a long press: rewind.

Useful when listening to podcasts and moving to the end of a commercial. Are these options common knowledge?

[Everyone should already know that two short presses skip forward in an increment of your choosing. Three short presses skip backward.]
