What variant of Codex are you using?
App (Codex desktop, macOS)
What feature would you like to see?
Add a keyboard shortcut and a command-palette/menu command to toggle Expand Panel for the built-in browser.
The expanded browser view is useful during browser-based development and testing, but currently it must be enabled repeatedly with the mouse. This interrupts keyboard-driven workflows.
The command should:
- Expand the currently open built-in browser panel when it is in its normal state.
- Restore the normal panel layout when the browser panel is already expanded.
- Have a default keyboard shortcut, or at minimum be exposed as a configurable command so users can assign one.
- Operate on the current built-in browser panel without opening a new browser when none is present.
Additional information
This request is specifically for toggling the existing Expand Panel state. It is different from #18726, which requested a shortcut to open the browser and side panel.
Observed on Codex desktop 26.715.72028 (build 5706) on Apple Silicon macOS.

+1 to this request. This is a high-frequency action in research and paper-reading workflows as well, not only browser-based development.
A common pattern is to keep a Codex conversation on the left and a built-in browser tab on the right with a PDF, GitHub issue, or documentation page. When reading math-heavy PDFs or long GitHub discussions, I often need to temporarily expand the browser panel to full width, then collapse it back to continue the Codex conversation. The current mouse-only top-right control works, but it breaks an otherwise keyboard-driven workflow.
A command exposed in Keyboard Shortcuts would already solve the problem, even if there is no default binding. The important part is being able to toggle the existing browser panel's expanded state without moving the mouse or opening a new browser tab.
