Pharo’s System Browser is the main interface to the Pharo programming system. It’s much like today’s IDEs such as Eclipse and IntelliJ IDEA, only much simpler and more elegant. To open the System Browser, left-click on open space to bring up the World menu, then select System Browser.
The System Browser consists of several panes: - the Packages pane is where you see all the logical groupings of classes - the Classes pane is where you see all the classes for a particular package - the Protocols pane is where you see the logical groupings of methods for a particular class - the Methods pane is where you see the methods for a particular protocol - the Edit pane is where you can view, edit, or create new methods and classes - the Quality Assistant pane is where you can see helpful hints and tips for whatever you are currently editing
