What it is
URL, Instant Copy is a zero-UI Chrome extension for grabbing the current tab link with one shortcut: Option + Shift + C on Mac, or Alt + Shift + C on Windows.
How it works
A Manifest V3 background service worker listens for the command, reads the active tab, and writes the URL through an offscreen document so clipboard access stays reliable. If the modern clipboard API is blocked, it falls back to the older copy path.
What shipped
- Shortcut-only URL copying with no host permissions.
- Offscreen clipboard handling with a fallback for stricter browser states.
- A small static popup that only reminds the user of the shortcut.
- Silent edge-case handling for missing tabs and repeated shortcut presses.
