tinykeys is a lightweight (≈650 bytes) JavaScript library that makes it easy to define modern keyboard shortcuts on web pages. It lets developers declare single keys, modifier combos, regex‑like groups and timed key sequences using a simple string syntax, and works across platforms with helpers like `$mod`. The package is aimed at front‑end developers who need a tiny, dependency‑free solution for handling keyboard interactions in vanilla JS, React, Svelte, or any other web framework.
