Thanks, Andrew!  In fact the Quick Reference was one of the first 
things I downloaded after being turned on to Squeak by Mark 
Guzdial's excellent tutorial book "Squeak: Object-Oriented Design 
with Multimedia Applications". 

The first thing I did after deciding to seriously undertake learning 
and using Squeak was to get everything I could find from the web, 
which included joining lists like this one, getting primers and intros 
and reference subsets such as the Quick Reference, and getting a 
used copy of David Smith's out-of-print book "IBM Smalltalk: the 
Language".  This book combines the approaches of Guy Steele's 
Common Lisp: the Lanuage" (as you might expect from the title) 
with a class encyclopedia.  It helps but is far from sufficient and is 
incorrect for Squeak in many places.  

All these things help but none suffice as a working reference for 
Squeak.
