Viewing information about a feature
Once you centered the editor on a feature, you have access to its text. The feature tab in the context tool can display more information. To have access to it, you have first to center the context tool on the wanted class and select the feature tab. You can then consult the different views of the text of the feature (basic text or flat) and other information such as its callers or its descendant versions.
The metric tool provides another kind of data. It enables you to compute some measures on your feature.
