• React keyboard shortcuts: the useKeybind hook

  Register a shortcut in one line, no manual useEffect/cleanup, no stale closures, inherently SSR-safe.

• Keyboard shortcuts in Next.js, SSR-safe

  App Router and Pages Router, without a "window is not defined" crash during server rendering.

• Building a Cmd/Ctrl+K command palette

  The cross-platform modifier alias, a dedicated scope, and closing on Escape while a search input is focused.

• Keyboard shortcuts inside a modal (and only there)

  Scoping bindings so background shortcuts can't fire behind an open dialog.

• Vim and Gmail-style key sequences

  Press g then g — sequences, timeouts, and how ambiguous sequences are resolved.

• Migrating from Mousetrap or hotkeys-js

  API mapping, what changes, and the one thing (simultaneous multi-key chords) that has no direct equivalent.
