| # Link-Preview |
| |
| ## Overview |
| The |
| [Link-Preview](https://docs.google.com/document/d/1hrWfVIDrPkrBlf8A576dDBH7Q34ESMLvOObt0j9i0SU/edit?usp=sharing) |
| feature allows users to quickly and safely preview linked pages in a small |
| window. While the user views the preview, Chrome actively prevents intrusive |
| behaviors, similar to the |
| [Prerendering](https://wicg.github.io/nav-speculation/prerendering.html) |
| feature, to ensure a secure preview experience. The preview window is |
| intentionally non-interactive (e.g., users cannot input text into a form or |
| click links) but can be promoted to a normal tab by clicking on it. |
| |
| ## Current Status |
| In the initial phase, we are conducting experiments with three different trigger |
| mechanisms (Alt + Click, Alt + Hover, Long Press) to determine the optimal |
| balance between usability and safety. |
| |
| ## Experiments |
| ### Enable the Feature |
| Users can manually enable the feature through chrome://flags/#link-preview. |
| |
| ### Experiment Groups |
| 1. Alt + Click trigger: Preview is triggered by pressing Alt and clicking a |
| link. |
| 2. Alt + Hover trigger: Preview is triggered by pressing Alt and hovering over |
| a link. |
| 3. Long Press trigger: Preview is triggered by pressing and holding a link. |
| |
| ## Feedback |
| We are |
| [gathering anonymous usage data](https://chromium.googlesource.com/chromium/src/+/main/tools/metrics/histograms/README.md) |
| during these experiments to assess the effectiveness of each trigger mechanism. |
| You don't need to provide explicit feedback on your preferred method, but if you |
| encounter any issues, please report them through |
| [this](https://crbug.com/343110535) crbug link. |
