HyperSpec
The main Lisp reference is HyperSpec. To find description of a symbol in
HyperSpec put a cursor at the symbol and hit Alt+H (or select HyperSpec in Lisp menu):
This will open a browser window in Eclipse with page describing the symbol:
LispDoc
The other good source of documentation is LispDoc. On its website it is described as "a search engine for documentation of the Common Lisp programming language and many of its libraries". When you request LispDoc search on a symbol with Alt+L (or LispDoc from Lisp menu) you get a page in a browser with example code of this symbol and a bunch of links to Lisp documents, books or manuals that mention this symbol:

examples below show how this feature works ( Notice how functions defined in
our code also display this information ):
Tooltips with quick documentation are also display when you hover mouse over
elements in outline:
Completion suggestions:
Cusp also support fuzzy way for proposing autocompletion, but it has to be turned on in preferences. To do this, open Windows->Preferences... menu, and set corresponding options:
Then typing m-v-b will suggest multiple-value-bind:
