Peek at a link
A Peek opens a link on top of the page you’re reading, without adding a tab. You close it to go back, or keep it if you want the page.
You’re reading a Fastmail thread with a link to a Codeberg issue, and you want a quick look before you answer.
- On the page, Option-click (Alt-click on Windows and Linux) the link.
- Read the page in the Peek.
- Press Escape to close the Peek.
To open a Peek from a link’s menu, right-click the link, then choose Open Link in Peek.
Keep the page
Section titled “Keep the page”In the bar at the top of the Peek:
- Open as tab keeps the page as a tab next to the one it came from, and shows it.
- Open in split shows the page next to the tab it came from, in a Split. When that tab is in a Split already, the page joins it. A Split of four pages has no room, and the button says so.
Details
Section titled “Details”- The Peek uses the sign-ins of the tab it opened from.
- The bar shows the page’s address.
- Clicking outside the Peek, or its close button, closes it too. So does switching to another tab, or the tab under it going to another page.
- A window shows one Peek at a time.
- A page you peeked at goes to History. It doesn’t go to recently closed tabs.
- A link you click in a pin that goes to another site opens in a Peek without Option. The bar then starts with “From” and the pin’s name.
- To turn off Option-click Peeks, go to Settings › Links › Links in pages and turn off the first switch. Option-click then does what the page expects, and Open Link in Peek leaves the link’s menu. Links from pins have a switch of their own there, Open links to other sites from a pin in a Peek.
