Stopping a running turn required hitting the small round Stop button. Esc now triggers thread.stop through the same interrupt path as that button.\n\nDialogs and menus close first, terminal focus is ignored, and the binding stays remappable in Keybindings settings.\n\nVerification: typecheck clean for web and shared; targeted unit tests pass (keybindings, settingsSearch, KeybindingsSettings logic — 198 tests).\n\nBuilt with Muse Spark via T3 Code.

Summary by CodeRabbit

  • New Features

    • Added Escape as the default shortcut for stopping an active thread when focus is outside the terminal.
  • Bug Fixes

    • Escape no longer stops a thread while a context menu, model picker, or floating selector is open. It also continues to work normally in terminal input.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — The PR adds Esc as a persisted default keybinding that can interrupt running agent turns and modifies production dialog/menu keyboard arbitration. This is a direct product-default and user-behavior change, so its rollout warrants human review.

📝 Walkthrough

Walkthrough

Escape now stops the thread outside terminal focus. ChatView skips stopping the thread when a context menu, model picker, or matching floating-layer element is present. Tests cover shortcut resolution, labels, editable settings rows, and settings search.

Changes

Escape thread stop behavior

Layer / File(s) Summary
Escape binding and settings coverage
packages/shared/src/keybindings.ts, apps/web/src/keybindings.test.ts, apps/web/src/components/settings/*
Escape maps to thread.stop when the terminal does not have focus. Tests cover shortcut resolution, platform labels, editable settings rows, and settings search results.
Overlay-aware stop handling
apps/web/src/components/ChatView.tsx
The thread.stop handler returns early for Escape when a context menu, model picker, or matching floating-layer element is present.

Ignore Escape during IME composition.

matchesShortcut does not check event.isComposing, so a composing Escape keydown can resolve to thread.stop. The Escape branch then prevents the event and interrupts the active thread. Return before the interrupt path when event.isComposing is true.

         if (event.key === "Escape") {
+          if (event.isComposing) return;

Note

This comment is posted by Julius' dot

This makes Escape stop a running turn by default. Stopping already works through the Stop button and configurable thread.stop command, so this changes the default interaction without linked maintainer approval. I'm closing it under prior approval. Get approval for the Escape behavior in an Ideas discussion and link it for reconsideration.
