JetBrains IntelliJ IDEA Keyboard Shortcuts

JetBrains IntelliJ IDEA is the leading commercial IDE for Java and Kotlin, used by 84% of Java developers in 2024 Stack Overflow surveys and a growing share of Scala, Groovy, and Python developers. IntelliJ pioneered the "Search Everywhere" (Shift+Shift) workflow that VS Code and others later copied, and remains the gold standard for refactoring shortcuts — every "Extract method/variable/field/parameter/constant" combo and the famous Shift+F6 Rename are IntelliJ originals. This reference card covers the most-used 100+ shortcuts across 8 functional areas: Common, Navigation & search, Editing, Selection, Refactoring, Run & debug, Version control (Git), Tool windows & misc. Linux keys are nearly identical to Windows; macOS replaces Ctrl with ⌘ and Alt with ⌥ while keeping Shift as ⇧. All entries are transcribed from JetBrains' official IntelliJ IDEA documentation. How to use - Pick your platform (Windows / Linux / macOS) at the top — keys change immediately. Default detected from User-Agent and saved to localStorage. - Type any word in the search box (e.g. "refactor", "debug", "git") to filter. Search matches feature names and keys on all platforms. - Click any row's Copy button to grab the current platform's key string. - Export PNG (2400×1140 landscape) for a printable wallpaper; PDF for a single A4 landscape page. Tips - Shift+Shift (Search Everywhere) is the single most useful shortcut — it searches classes, files, symbols, actions, and even recent files at once. - Alt+Enter (Show intention actions) fixes warnings, optimizes imports, generates code. Combine with Ctrl+Shift+A (Find Action) to discover anything. - Ctrl+W / Ctrl+Shift+W extend/shrink selection intelligently — start at the cursor, grow to word → expression → line → block → method. - Ctrl+Alt+L reformat code to project style; Ctrl+Alt+O optimize imports. Both run on save if enabled. Why this separate from vscode-shortcuts? IntelliJ's shortcut ecosystem is built around Java/Kotlin refactoring and IDE tool windows — a different world from VS Code's editor-centric model. Mixing them would dilute both tools. This separation keeps each printable as one page.
