### 3.6 Documentation commands ¶

SLIME’s online documentation commands follow the example of Emacs Lisp. The commands all share the common prefix `C-c C-d` and allow the final key to be modified or unmodified (see Key bindings.)

`SPC` ¶
`M-x slime-space`

  The space key inserts a space, but also looks up and displays the argument list for the function at point, if there is one.

`C-c C-d d` ¶
`M-x slime-describe-symbol`

  Describe the symbol at point.

`C-c C-d f` ¶
`M-x slime-describe-function`

  Describe the function at point.

`C-c C-d A` ¶
`M-x slime-apropos`

  Perform an apropos search on Lisp symbol names for a regular expression match and display their documentation strings. By default the external symbols of all packages are searched. With a prefix argument you can choose a specific package and whether to include unexported symbols.

`C-c C-d z` ¶
`M-x slime-apropos-all`

  Like `slime-apropos` but also includes internal symbols by default.

`C-c C-d p` ¶
`M-x slime-apropos-package`

  Show apropos results of all symbols in a package. This command is for browsing a package at a high-level. With package-name completion it also serves as a rudimentary Smalltalk-ish image-browser.

`C-c C-d h` ¶
`M-x slime-hyperspec-lookup`

  Lookup the symbol at point in the Common Lisp Hyperspec. This uses the familiar `hyperspec.el` to show the appropriate section in a web browser. The Hyperspec is found either on the Web or in `common-lisp-hyperspec-root`, and the browser is selected by `browse-url-browser-function`.

  Note: this is one case where `C-c C-d h` is not the same as `C-c C-d C-h`.

`C-c C-d ~` ¶
`M-x hyperspec-lookup-format`

  Lookup a format character in the Common Lisp Hyperspec.

`C-c C-d #` ¶
`M-x hyperspec-lookup-reader-macro`

  Lookup a reader macro in the Common Lisp Hyperspec.
