This subsection describes the commands that find references to identifiers and perform various queries about identifiers. Each such reference could define an identifier, e.g., provide the implementation of a program subunit or the text of a document section; or it could use the identifier, e.g., call a function or a method, assign a value to a variable, mention a chapter in a cross-reference, etc.
