This document discusses how to use estar and present participles to indicate that something is happening now in Spanish. It explains that estar is conjugated normally and combined with the present participle, formed by dropping the infinitive ending and adding -ando, -iendo, or -yendo. Examples are provided such as "Cora está escuchando los discos" to say "Cora is listening to CDs." This construction is used less frequently in Spanish than in English to specifically denote an ongoing action.
