Every launch Googlebook keyboard turns F1, F2, and F3 into dedicated Android navigation keys, giving the Googlebook physical navigation buttons a permanent spot on the hardware instead of leaving them as onscreen taps.
The layout is identical across all five launch models, according to The Verge's hands-on report published Oct. 7, 2026.
Those same keyboards also carry over two keys from Chromebooks: Quick Insert and the Google logo key. Neither is a Googlebook invention, since both debuted on select Chromebook models a couple of years earlier, according to The Verge.
This applies to all five launch Googlebooks, regardless of chipset. Here's what each F1-F3 navigation button does, which parts of the keyboard are genuinely new versus inherited from Chromebooks, and a separate chip-related caveat worth knowing before choosing between models.
How Googlebook physical navigation buttons handle back, home, and app switching
These Googlebook keyboard navigation keys use the triangle, circle, and square icons Android introduced with Android 5.0 Lollipop in 2014, when they became the default onscreen navigation buttons.
The icons represent Back, Home, and the app switcher. Android 17 still offers three-button navigation as an alternative to gestures, according to The Verge.
Readers coming from a gesture-first phone may not have touched a button layout like this in years. The actions themselves are familiar. They've simply moved from onscreen controls to dedicated keys in the function row.
On Googlebook OS, the three keys perform these actions:
F1, triangle (Back): Returns to the previous screen or navigational step.
F2, circle (Home): Minimizes all open apps to show the desktop.
F3, square (App switcher): Tiles open apps into an overview that The Verge compares to Mission Control on macOS or Task View on Windows.
Home and the square key aren't interchangeable, and mixing them up is an easy early mistake. Home clears the desktop of open windows without closing the apps, while the square key provides an overview for switching between them.
The Verge also notes that Home isn't a toggle. Pressing it a second time doesn't restore minimized apps to their previous positions. That requires a separate Googlebook OS keyboard shortcut for desktop peeking.
The Back button fills a specific gap. The Verge found it sometimes necessary when using Android apps that weren't designed for a mouse or desktop interface and lacked an obvious onscreen back control.
That's an observed workaround rather than a guarantee for every app in the Play Store.
Longtime Android users may recognize the familiar navigation icons from older phones. Their return as physical keys is unusual, but the arrangement also serves a practical purpose for apps originally designed around touch navigation.
Since the layout matches across all five launch Googlebooks, muscle memory from one model should carry over to another without relearning the controls.
That consistency means the navigation row isn't a factor buyers need to weigh when comparing the launch models.
Quick Insert and the Google key aren't new, even if the navigation row is
It's a common misconception that Quick Insert and the Google logo key are Googlebook-specific additions, according to The Verge.
They aren't. Both keys debuted on select Chromebooks a couple of years before Googlebooks arrived.
The genuinely new part of the Googlebook keyboard is the physical Android navigation row, which brings the familiar phone controls into the F1, F2, and F3 positions.
That distinction matters for anyone comparing a Googlebook with a Chromebook they've already used.
If Quick Insert and the Google key felt familiar on a Chromebook, their presence on a Googlebook won't be surprising. The main difference is the dedicated Android navigation row.
And because that row works identically across the five launch models, there's no model-specific navigation layout to research before buying.
Separate buying caveat: Android app performance on Intel chips
A separate issue, unrelated to the keyboard, concerns Android app performance across Googlebook chipsets.
In a statement to Android Authority cited by The Verge, Google said:
The vast majority of Android apps run smoothly across both Intel and Qualcomm Googlebooks right out of the box. Because many Android apps were originally designed for Arm chips, a small handful of complex apps or games need some developer tuning to run their best on Intel-based platforms.
Google also said it was working with developers, Intel, and Qualcomm to improve performance and compatibility.
The company didn't name the affected apps or specify how many require additional optimization.
Of the five Googlebook models available at launch, three from Acer, Asus, and Lenovo use Intel x86 processors. The Dell and HP models use Arm-based Qualcomm Snapdragon chips.
The Verge suggested the Snapdragon models should have fewer compatibility issues with Android apps originally designed for Arm processors. However, that expectation isn't a substitute for independent testing of specific apps and workloads.
The outlet said it planned to test all five Googlebooks and report any problems it identified. Its Oct. 5 report didn't include those results.
The keyboard layout remains consistent regardless of chipset, so the navigation row and inherited Chromebook keys don't factor into this part of the buying decision.
App compatibility is a separate consideration, especially for buyers who depend on demanding Android games or specialized applications.
Buyers comparing Googlebook models can treat the F1-F3 navigation row as consistent across the launch lineup.
The more important question is whether the Intel-based Acer, Asus, and Lenovo models run the apps they need as smoothly as the Snapdragon-powered Dell and HP alternatives.
Google says only a small number of complex apps and games need additional tuning, but without a published list or matched-condition testing, the size of any performance gap remains unclear.
Before buying, check recent testing of the exact Googlebook model and Android apps you plan to use rather than assuming that every Intel-based device will have compatibility problems.
