Multitasking on ChromeOS often requires keeping reference documents, chat applications, calculators, or video streams visible whilst browsing through multiple browser tabs or working across different virtual desks. Rather than splitting your screen in half and sacrificing horizontal workspace, ChromeOS includes a dedicated Float Window feature. This mode detaches an active application window, resizes it into a compact floating frame, and pins it on top of all other open windows.
When an application is floated, it remains pinned above your other windows even when you switch active applications, navigate between different browser windows, or transition between virtual desks. You can freely reposition the floating window, adjust its size, or restore it to standard tiling layout at any time.
How to Float a Window Using Window Controls
The quickest visual method to float an active window on a Chromebook is through the integrated window management menu located in the title bar.
- Open the application or browser window that you wish to keep pinned on top of your screen.
- Hover your cursor over the Maximise/Restore button (the square or rectangle icon) located in the upper-right corner of the window. A pop-up menu showing various window layout presets will appear.
- Locate the Float option, represented by an icon showing a smaller window floating in the bottom-right corner of a larger display frame.
- Click the Float icon. The window will immediately shrink into a compact format and pin itself in the lower-right corner of your desktop.
How to Float a Window Using Keyboard Shortcuts
If you prefer navigating your system without taking your hands off the keyboard, ChromeOS provides a direct keyboard combination to toggle floating windows instantly.
- Click inside the application window you want to float to ensure it has active focus.
- Press the key combination Search + Alt + F (or Launcher + Alt + F depending on your keyboard layout).
- The active window will immediately detach and float above your underlying workspaces.
- To unfloat the window and return it to its previous tiled or maximised state, press Search + Alt + F again while the floating window has focus.

Repositioning and Resizing a Floating Window
Once a window is floating, ChromeOS allows you to adjust its placement and dimensions to keep your primary workspace unobstructed.
- Moving the window: Click and hold anywhere along the top title bar of the floating window, then drag it across your display. You can position it in any corner or edge of your screen.
- Resizing the window: Move your cursor to any border or corner of the floating window until the cursor changes into a double-ended arrow. Click and drag outward to expand the window or inward to shrink it to the minimum supported dimensions.
- Snapping to corners: Dragging a floating window near the edges or corners of the screen prompts ChromeOS to automatically align it neatly against the display boundary.
Interacting with Virtual Desks and Split Screen
The floating window mechanism integrates seamlessly with broader ChromeOS productivity tools:
- Persistent across Virtual Desks: Unlike standard windows that reside exclusively on a single desk, a floating window stays visible as you switch across your virtual desks. This makes it ideal for persistent timer apps, music players, or reference notes.
- Compatibility with Split Screen: You can combine floating windows with split-screen layouts. For instance, you can snap two full-sized documents side by side and maintain a third floating calculator or notepad on top. For complementary multitasking techniques, read our guide on how to use split screen and snap layouts on Chromebook.
- Minimising floating windows: If you temporarily need unobstructed access to your underlying screen, click the standard Minimise button on the floating window. It will collapse into the ChromeOS shelf (taskbar) and retain its floating state when reopened.
Troubleshooting Common Floating Window Issues
If the float window option does not behave as expected, consider the following troubleshooting steps:
- Fixed-size Android applications: Certain mobile apps ported to ChromeOS via the Google Play Store have rigid viewport requirements that do not support dynamic window resizing or floating. If the Float icon is greyed out or absent, the app developer has restricted multi-window modes.
- Full-screen mode conflict: If an application is running in immersive full-screen mode (such as after pressing the dedicated full-screen key in the top function row), floating controls are suppressed. Press the full-screen key or Esc to return to windowed mode before floating.
- ChromeOS version requirements: The Float Window feature is built natively into ChromeOS version 108 and later. If you do not see the layout menu upon hovering over the maximise button, navigate to Settings > About ChromeOS > Check for updates to ensure your operating system is up to date.
