🎯 Changes

Fixes #142. Global hotkeys and sequences now preserve unmodified Space/Enter activation on native buttons and Enter on links when ignoreInputs is enabled. Explicit element targets, ignoreInputs: false, modifier shortcuts, and unrelated keys retain their behavior. Includes updated guides, generated reference docs, and a patch changeset. ARIA composite widget ownership in #138 remains a separate issue.

Validation: pnpm test and pnpm test:pr passed; all 631 core tests passed, including 42 new regression cases. Fifteen Chromium keyboard checks verified native clicks, shadow DOM, window targets, sequences, and overrides. Package size: 10.48 kB / 12 kB.

✅ Checklist

  • I have followed the steps in the Contributing guide.
  • I have tested code changes locally with pnpm run test:pr, or these tests do not apply to this pull request.
  • I fully understand the code in this pull request, including any code generated with AI assistance.

🚀 Release Impact

  • This change affects published code, and I have generated a changeset.
  • This change is docs/CI/dev-only (no release).

Summary by CodeRabbit

  • Bug Fixes
    • Global hotkeys and sequences now preserve native Space and Enter activation on buttons and button-type inputs, and Enter activation on links. Other shortcuts remain available on these controls.
    • Explicit element targets or ignoreInputs: false can still handle these activation keys.
  • Documentation
    • Clarified keyboard behavior across framework guides, including that custom ARIA widget behavior is not detected automatically.

📝 Walkthrough

Walkthrough

When input filtering is enabled for global hotkeys and sequences, unmodified activation keys remain available to native buttons, button-type inputs, and links with an href. Tests and framework guides describe the behavior, its overrides, and its limits.

Changes

Native activation filtering

Layer / File(s) Summary
Activation filtering and coverage
packages/hotkeys/src/_event-target.ts, packages/hotkeys/src/hotkey-manager.ts, packages/hotkeys/tests/native-activation.test.ts, docs/framework/*/guides/hotkeys.md, .changeset/tidy-tigers-swim.md
The event filter exempts unmodified Space and Enter on buttons and button-type inputs, and Enter on links and areas with an href, for document and window registrations. Tests cover both managers, sequences, explicit targets, overrides, and related key cases. The framework guides and changeset describe the behavior.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix · Severity of issue fixed: Medium

Merge Risk: 🔵 Low · up to 04996

Keyboard activation can be blocked for buttons inside closed shadow roots. A configuration workaround is available; document the limitation across the guides and public option description.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 04996

Native controls gain protection from global activation shortcuts, but a control activation can now leave an in-progress shortcut sequence active until its timeout. A later key could complete that sequence. No privilege bypass or sensitive operation is established by the reviewed code.

Retained concerns

  • Low · architecture · inferred: A newly ignored native-control activation leaves an already-started global sequence armed. Its next expected key can invoke the application callback before the sequence timeout, whereas a previously eligible mismatched activation could reset progress. The consequence depends on the callback registered by the application.
Security review details

Security Blast Radius

  • inferred — Exposure is through document/window keyboard registrations in applications using this package. The reviewed path reaches application-provided callbacks, not an identified built-in credential, network, or authorization operation.

Security Findings and Attack Paths

  • inferred — A later expected key can complete a sequence after an ignored native activation, but the reviewed code does not establish an attacker-controlled way to gain authority or identify a sensitive callback. Security impact is application-dependent, not a verified exploit.

Trust Boundaries and Controls

  • observed — The exception requires a global registration, no modifier keys, and a recognized native control. Existing ignoreInputs and preventDefault options remain controls over handling and cancellation.

Resilience and Maintainability Implications

  • observed — Sequence completion clears progress before invoking the callback. Timeout and eligible mismatches also reset progress, but an ignored event reaches neither reset path.

Hardening Proposals

  • proposed — Define whether activating a native control should interrupt an armed sequence, particularly where applications bind sensitive actions to sequences; make the state transition explicit if interruption is required.
  • proposed — Qualify the published native-activation guarantee for controls inside closed shadow roots unless their behavior is separately established; the current regression test covers an open root.

Explanation

Issue #142 requires native activation for button-like controls, including checkboxes, while a global short-key hotkey is active. The PR preserves unmodified Space and Enter for native buttons and button-type inputs, and preserves Enter for links with an href. The described implementation does not include native checkboxes, and the listed regression tests do not establish checkbox coverage.

A rabbit taps Space, then Enter with care
The button still clicks; the link answers there
With other keys, hotkeys can play
And sequences wait till the keys say
Hop, native actions stay on their way

Document the closed-shadow-root limitation in every ignoreInputs description.

The global listener cannot identify a native button inside a closed shadow root. An unmodified Space or Enter hotkey can therefore call preventDefault() and block native activation. Add the limitation and the { preventDefault: false } workaround to all seven framework guides and the public ignoreInputs description in packages/hotkeys/src/hotkey-manager.ts, not only React and Solid.

Suggested documentation update
 When `ignoreInputs` is enabled, global hotkeys and sequences (targeting `document` or `window`) also preserve unmodified `Space` and `Enter` on native buttons and button-type inputs, and `Enter` on links with an `href`.
+Controls inside closed shadow roots are not visible to the global listener. Set `preventDefault: false` to preserve native activation while keeping the hotkey callback.
