The #select: block needs the code inside it to return a boolean, so the #notNil converts the response from the #firstOwnerSuchThat: method into a boolean rather than leaving it as either nil or the morph. If you right click on a method and choose Implementors you can see how each class that implements the method defines it. You can also right click the method and choose Senders to see examples of how the method is used.

Understanding ConfigurationBrowser

by Frank Church

On using the ConfigurationBrowser I want to understand certain things. What is the difference between the packages in the Configurations and Untrusted columns. Are those in the Configurations column tested for the particular release and the converse for the Untrusted ones? I have compared the one for Pharo 2.0 vs 1.4 and the far fewer in the Configurations column with Pharo 2.0 -- Frank Church ======================= http://devblog.brahmancreations.com

The default setting is to use TAB to accept a suggestions. You can change it to enter by looking for "completion" in the settings browser.
