9. A computer-implemented method comprising: under direction of one or more hardware processors configured with specific software instructions, receiving, from a user interacting with a textual record including one or more nodes and one or more subnodes, a first input including a command and a node identifier; in response to receiving the command and the node identifier: identifying, based on the node identifier, a node of the textual record associated with the node identifier; determining a first portion of the textual record related to the identified node; and selecting the first portion of the textual record; receiving, from the user interacting with the textual record, a second input including the command and a subnode identifier; and in response to receiving the command and the subnode identifier: identifying, based on the subnode identifier, a subnode of the textual record associated with the subnode identifier; determining a second portion of the textual record related to the identified subnode; and selecting the second portion of the textual record.

The computer-implemented method of claim 9 , wherein determining the first portion of the textual record is based on one or more selection rules, and wherein the one or more selection rules include at least one of: a rule useable to identify a node, a rule useable to identify a start point and end point of the first portion of the textual record, or an action to take with respect to the first portion of the textual record.
