Pull request overview
This PR migrates the web app’s keyboard shortcut handling from react-hotkeys-hook (and some custom global keyboard plumbing) to TanStack Hotkeys, aiming to reduce custom maintenance while keeping existing shortcut behavior working.
Changes:
- Added
@tanstack/react-hotkeysand removedreact-hotkeys-hook. - Updated form and calendar shortcut hooks/components to register TanStack hotkeys and normalized several key combo strings (e.g.,
$mod,arrow*). - Refactored
useKeyboardEventto delegate to TanStack Hotkeys and updated its unit tests accordingly.

exactMatchis destructured with a default (exactMatch = true) but never used. WithnoUnusedLocals: truein tsconfig, this will fail TypeScript compilation. Either implement theexactMatchbehavior (to preserve the prior API) or remove it from the options/destructuring to avoid the unused local.

Thanks for the PR. However, e2e tests are failing and there are valid PR comments

The useSetupKeyboardEvents function is now a no-op, but the old RxJS-based event system (keyPressed$, keyReleased$, globalOnKeyPressHandler, globalOnKeyUpHandler) is still used by other parts of the codebase. Critically, the pressKey utility (used in multiple test files and in production code like CmdPalette.tsx and DayCmdPalette.tsx) dispatches events to window, while TanStack Hotkeys listens on document. This means:
-
Broken tests:
useDayViewShortcuts.test.ts,useNowShortcuts.test.ts,useGlobalShortcuts.test.ts, andDayCmdPalette.test.tsxall usepressKey()to simulate keyboard events through the old system. SinceuseKeyboardEventno longer subscribes tokeyPressed$/keyReleased$, these tests will fail. Runyarn test:webto confirm. -
Broken production code:
CmdPalette.tsx,DayCmdPalette.tsx, andNowCmdPalette.tsxcallpressKey()to programmatically trigger shortcuts (e.g.,onClick: () => pressKey("z")). These will no longer trigger the corresponding shortcut handlers since the RxJS pipeline is disconnected.
The migration needs to also update pressKey to dispatch to document instead of window, and the dependent tests need to be updated or the test approach needs to change.

The exactMatch option is still accepted in the Options interface (line 8) but is never used in the new implementation. It's destructured on the equivalent of line 45 but silently discarded. This is a behavioral regression: useDayViewShortcuts.ts (lines 150, 157) passes exactMatch: false to useKeyDownEvent for migration shortcuts, which previously allowed superset key combinations to match. With TanStack Hotkeys, the matching behavior is entirely controlled by the library and exactMatch has no effect. Either remove exactMatch from the Options interface (and update callers) or implement equivalent behavior.

The tests have been rewritten from integration-style tests (dispatching real keyboard events and observing outcomes) to implementation-detail tests (mocking useHotkey and inspecting mock calls). This violates the testing guidelines in AGENTS.md which state: "Write tests the way a user would use the application by using the DOM and user interactions" and "When writing tests, avoid mocking as much as possible." The previous tests were closer to these guidelines. Consider testing with real keyboard events via @testing-library/user-event and verifying the handler callbacks were invoked, rather than mocking the entire TanStack Hotkeys library.

The comment says "Dispatch a keyboard shortcut to the window" but the code now dispatches events to document instead. Update the JSDoc to say "Dispatch a keyboard shortcut to the document" to match the actual behavior.
Description
Replaced the existing custom keyboard shortcut implementation with TanStack Hotkeys library. This migration reduces the amount of custom code we need to maintain while leveraging a well-tested, production-ready hotkeys solution. TanStack Hotkeys provides a cleaner API and better support for advanced use cases like sequence shortcuts.
The migration involved:
Closes #1472.
The code in this pull request was generated by GitHub Copilot with the Claude Sonnet 4.5 model.
