IntelliJ Shortcuts for Pairing

The macOS (default) keymap. Symbols: ⌘ Cmd · ⌥ Option · ⌃ Control · ⇧ Shift · ↩ Enter · ⌫ Delete. Keep this open on your second monitor while you mob.

The escape hatch Forget a shortcut? ⇧⇧ (Search Everywhere) or ⌘⇧A (Find Action) run any command by name. Learn these two and you can always find the rest.

1 · The TDD loop (learn these first)

Keys	Action	Why it matters here
⌃⇧R	Run test/class under caret	Run the one test you're driving
⌃R	Re-run last	The green-refactor heartbeat
⌘⇧T	Jump class ⇄ test	`Hand` ⇄ `HandValueAceTest`
⌥↩	Intention actions / quick-fix	Create the missing method/class the failing test names
⌘N	Generate (in editor)	Constructor, `equals`/`hashCode`, override, Test…
⌃⌥O · ⌘⌥L	Optimize imports · reformat	Tidy before you hand over

2 · Navigation (a hexagonal codebase has many small files)

Keys	Action
⇧⇧	Search Everywhere — double-tap Shift
⌘O	Go to class (`GameService`)
⌘⇧O	Go to file (`pom.xml`, a Thymeleaf `.html`)
⌘⌥O	Go to symbol (method/field by name)
⌘B / ⌘-click	Go to declaration → then usages
⌥⌘B	Go to implementation (`Deck` → `StubDeck`, `OrderedDeck`)
⌘E	Recent files · ⌃Tab switcher
⌘[ / ⌘]	Navigate back / forward
⌘F12	File structure (methods in this file)
⌘1 · ⎋	Toggle Project window · return to editor

3 · Editing & refactoring

Keys	Action
⇧F6	Rename (safe, everywhere)
⌥⌘M	Extract method
⌥⌘V / ⌥⌘C / ⌥⌘F / ⌥⌘P	Extract variable / constant / field / parameter
⌃T	Refactor This… menu
⌘D / ⌘⌫	Duplicate / delete line
⌥↑ / ⌥↓	Extend / shrink selection
⌃G	Add next occurrence (multi-cursor)
⌘/ · ⌘⌥/	Line · block comment
F2 / ⇧F2	Next / previous error

4 · Running & Git (git-handover pairing)

Keys	Action
⌃⇧R / ⌃⇧D	Run / Debug class under caret
F8 / F7	Step over / into (debugger)
⌘K / ⌘⇧K	Commit / Push
⌘T	Update project (pull)
⌘9	Git tool window
⌃⌃	Run Anything

Ensemble handover — your team rotates via git (mob)

The mob tool is installed. In the repo terminal (⌥F12 opens IntelliJ's terminal):

mob start 10        # begin session, 10-min turns; pulls the mob branch
# ...you type while the mob directs...
mob next            # commit WIP & hand the keyboard to the next person
mob done            # squash the mob branch back onto master, ready to commit as one change

Everyone runs mob start to receive the baton; the typist runs mob next when the timer rings. See mob.sh.

Two Mac gotchas

Mission Control steals ⌃↑/⌃↓/⌃←/⌃→. If IntelliJ's caret/tab moves don't work, turn them off in System Settings → Keyboard → Keyboard Shortcuts → Mission Control.

F-keys: if F2/F7/F8 change brightness/volume, add fn, or tick “Use F1, F2… as standard function keys.”

Primary source

JetBrains keeps the authoritative, always-current list: Mastering keyboard shortcuts, and the printable IntelliJ IDEA Reference Card (PDF). In-app: ⌘⇧A → “Keymap” shows and lets you rebind anything. Tip: enable Key Promoter X (plugin) to learn shortcuts as you click.

Want me to rebind anything (e.g. a one-key Code With Me or a “run all tests” chord), or export this keymap so the whole ensemble shares it? Ask me.
