1. vi. To go through multiple levels of indirection, as in traversing a linked list or graph structure. Used esp. by programmers in C, where explicit pointers are a very common data type. This is techspeak, but it remains jargon when used of human networks. “I'm chasing pointers. Bob said you could tell me who to talk to about....” See dangling pointer and snap.

2. [Cambridge] pointer chase or pointer hunt: The process of going through a core dump (sense 1), interactively or on a large piece of paper printed with hex runes, following dynamic data-structures. Used only in a debugging context.
