Lens registers four commands. Chrome owns the bindings, so they are changed in Chrome rather than in the extension.
| Command | macOS | Windows / Linux | What it does |
|---|---|---|---|
| Capture region | ⌘⇧S | Alt+Shift+S | Opens the region selector |
| Capture full tab | ⌘⇧F | Alt+Shift+F | Captures the visible tab with no selection step |
| Record steps | ⌘⇧E | Alt+Shift+E | Starts a walkthrough — a screenshot per click, no video, no time limit |
| Record GIF region | ⌘⇧R | Alt+Shift+R | Opens the region selector ready to record |
1. Inside the save screen
These are not Chrome commands and cannot be rebound — they belong to the editor that opens after a capture.
| Key | What it does |
|---|---|
| ⌘S / Ctrl+S | Save into the project folder |
| ⌘Z / Ctrl+Z | Undo the last mark, crop, rotation or adjustment |
| Escape | Leave the tool you are in; on an unedited picture, close the save screen |
| Shift | Held while dragging, constrains a shape — a square, a circle, a straight line |
| Enter | In the file name field, saves |
2. Changing a shortcut
- Open chrome://extensions/shortcuts or follow the link at the top of the Settings page on the dashboard.
- Find Lens in the list each command has its own row.
- Click the field and press the combination Chrome refuses combinations already taken by the browser or another extension.
Chrome allows a limited number of suggested shortcuts per extension, and any command can be left unbound. An unbound command shows as not set on the Settings page; the popup buttons still work.
3. When a shortcut does nothing
- The tab is a page Chrome does not allow extensions on — chrome:// pages, the Web Store, the PDF viewer. The toolbar icon shows a red ! and its tooltip explains why.
- Another extension has claimed the same combination. Chrome gives it to whichever registered first; rebind one of them.
- The page has not finished loading. Wait for it and try again.
