### 3.7 Cross-reference commands

SLIME’s cross-reference commands are based on the support provided by the Lisp system, which varies widely between Lisps. For systems with no built-in XREF support SLIME queries a portable XREF package, which is taken from the CMU AI Repository and bundled with SLIME.

Each command operates on the symbol at point, or prompts if there is none. With a prefix argument they always prompt. You can either enter the key bindings as shown here or with the control modified on the last key, See Key bindings.

`C-c C-w c` ¶
`M-x slime-who-calls`

  Show function callers.

`C-c C-w w` ¶
`M-x slime-calls-who`

  Show all known callees.

`C-c C-w r` ¶
`M-x slime-who-references`

  Show references to global variable.

`C-c C-w b` ¶
`M-x slime-who-binds`

  Show bindings of a global variable.

`C-c C-w s` ¶
`M-x slime-who-sets`

  Show assignments to a global variable.

`C-c C-w m` ¶
`M-x slime-who-macroexpands`

  Show expansions of a macro.

`M-x slime-who-specializes` ¶

  Show all known methods specialized on a class.

There are also “List callers/callees” commands. These operate by rummaging through function objects on the heap at a low-level to discover the call graph. They are only available with some Lisp systems, and are most useful as a fallback when precise XREF information is unavailable.

`C-c <` ¶
`M-x slime-list-callers`

  List callers of a function.

`C-c >` ¶
`M-x slime-list-callees`

  List callees of a function.
