Using the IDE Feature Trainer
Learning new things in the IDE
Modules and Lessons
Modules are logical groupings of lessons. Each lesson can be completed in any order and restarted as many times are you like. Lessons will help you to associate actions and keyboard shortcuts with functionality in the IDE.
The IDE Feature Trainer is a great way to learn about features, workflows and keyboard shortcuts in IntelliJ IDEA. You do not need to complete the modules or lessons in order, allowing you to fit your learning around your schedule.
