This Quick Reference Guide was originally created by Andrew Greenberg, and was extensively revised by Andrew Black in May 2001 in preparation for a Tutorial at ECOOP.
The quick reference is now in two parts.
Please note that both parts are now over ten years out of date and in need of some reworking!
The Classes Reference (older versions: htmlpdf), including a summary of the basic numeric, string, collection and stream classes, and some more advanced material, e.g., on exceptions.
If you find errors in this material, or have suggestions for improvement, please send email to Andrew Black.
Note that the help system in current Squeak versions includes
a terse guide to Smalltalk
keyboard short cuts
useful expressions.
an explanation of the subsystems with links to important classes.
