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.)

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.
