Elgin on understanding: How does it involve know-how, endorsement and factivity?

In Chapter 3 of True Enough, Elgin (2017) outlines her view of objectual understanding, focusing largely on its non-factive nature and the extent to which a certain kind of know-how is required for the "grasping" component of understanding. I will explore four central issues that feature in this chapter, concentrating on (1) the role of know-how, (2) the concept of endorsement, (3) Elgin's critique of the factivity constraint on understanding, and (4) how we might use aspects of Elgin's framework to inform related debates on the norm of assertion.
