IntelliJ IDEA Cheatsheet - Java IDE Shortcut Reference

IntelliJ is powerful enough to be slow to learn; the shortcuts are the unlock. This reference groups navigation, editing/refactoring, generation/completion, run/debug stepping, VCS and layout. It flags high-yield keys like Search Everything, Generate, and Rename across the hierarchy, plus the debugger stepping set. For Java/Kotlin work where jumping between related classes and runtime state is constant. After reading you navigate, refactor and debug without breaking to the mouse.

Tips

  • Shift+Shift quickly searches anything (classes, files, symbols, actions).
  • Before Cmd+Alt+L reformats code, set up the Code Style first.
