'Show Example Network' that opens a network where you can see the use of the module in context of other modules that are needed for a particular module to work
'Show Help' that opens the HTML help of the module with more information about the module and its fields
Most of the fields of modules have a tooltip that briefly explains the use of that field.
The field's context menu has the entry 'Show Field Help' that opens the module's HTML help and scrolls to the entry of that field's help.
MeVisLab is shipped with a number of example macro modules that demonstrate the use of GUI controls, such as buttons, sliders, layouters, or even more complex controls like a GraphicsView or an ItemModelView.
There is a user forum where you can register for free and ask questions concerning certain modules or networks, or the development of modules. You can also report bugs that you found or exchange experiences with other users. Make sure to use the forum's search before posting a question; your question might already have been answered!
