This is the kind of Being that underlies everything we do. When we are immersed in action toward some present-at-hand goal we are engaged with the ready-to-hand aspects of the world as the means for the satisfying of that goal.
This is the kind of Being that Heraclitus, Hegel, and Nietzsche continually spoke of in their emphasis on Becoming instead of Being.
It expresses itself as the kind of Being that signs that make up symbols or the content of forms as studied by structuralism have.
It is expressed in the ready-to-hand modality of being-in-the-world.
This kind of Being exists at the second meta-level above Pure Presence and below Hyper
Being.
