My tips for using IntelliJ IDEA effectively

I wanted to share my tips and tricks that and especially keyboard shortcuts that make me more productive when using IntelliJ IDEA. IntelliJ is my favorite IDE and a very well thought-out program in general, and despite trying to learn the countless shortcuts available, there are a few that give you the biggest productivity boost already.

My frequently used features and shortcuts that I showed in the video are:

Coding

• IdeaVIM
• Live templates (e.g. main → public static void main( …​)
• Postfix completion (e.g. "Hello".sout → System.out.println("Hello");)
• Ctrl+Space:  Basic code completion
• Ctrl+Shift+Enter:  Complete current statement
• Alt+Enter:  Show context actions (aka “quick fix”)
• Ctrl+Alt+L:  Reformat code (and optimize imports when activated)
• Ctrl+B:  Go to declaration / usage
• Ctrl+Shift+B:  Go to implementation(s)
• Ctrl+U:  Go to super method
• Alt+Insert:  Generate code
• F2:  Next highlighted error

• Ctrl+Alt+N:  Inline
• Ctrl+F12:  File structure (e.g. list of methods)

Navigating

• Ctrl+N:  Go to class
• Ctrl+Shift+N:  Go to file
