Glance Peek — Preview Links Without a Tab

Glance Peek lets you read any linked page without leaving your current tab. Shift+Click a link and the target opens in a full-screen overlay — you get full, scrollable access to the page content. When you’re done, dismiss the overlay to return to exactly where you were, or promote the preview to a full tab if it’s worth keeping. It’s Arc’s Peek feature, available in Chrome.

How It Works

Shift+Click triggers an overlay iframe that covers the current tab. The target URL loads in full inside the iframe — including JavaScript, images, and interactive content.

Many websites use X-Frame-Options or Content-Security-Policy headers to block being displayed inside iframes (a standard anti-clickjacking measure). For Glance Peek to work reliably, SuperchargeNavigation uses Chrome’s Declarative Net Request API to create dynamic session rules that strip these blocking headers for the preview request. These rules are active only during the peek and are scoped to the preview session — they do not affect normal browsing.

When to Use This

Reading news or articles: You’re scanning a list of links and want to check a few before deciding which to read in full. Shift+Click each one, read the gist, close what you don’t need, promote what you do.

Research: You’re on a search results page or a resource list. Glance Peek each link without accumulating a pile of open tabs. Decide as you go.

Checking references: You’re writing or researching and want to verify a linked source without context-switching away from your current page.

Complement to Super Drag: Super Drag opens links in background or foreground tabs; Glance Peek opens them in overlays. Together they cover every link-opening pattern — no tab required, background tab, or foreground tab — all from keyboard modifiers and drag direction.

Privacy

Glance Peek loads the linked page directly from its origin. The extension does not intercept, log, or transmit any content from the previewed page. The dynamic DNR rules used to strip framing headers are session-scoped and discard no browsing data.
