Handling of BrowserBack and other similar keys

[Leon99]

Is your feature request related to a problem? Please describe.
My app needs to perform an action on pressing BrowserBack button. WPF can handle such keys like this:

    <Window.CommandBindings>
        <CommandBinding Command="BrowseBack" Executed="CommandBinding_OnExecuted"></CommandBinding>
    </Window.CommandBindings>

That doesn't exist in Avalonia.

Describe the solution you'd like
Not sure if Window.CommandBindings is necessary. Perhaps extend the regular KeyBinding to support Gesture="BrowserBack"?

Describe alternatives you've considered
Use native interop perhaps?

Additional context

This still does not work in 2026 (Windows, using mouse keys)

<Button HotKey="BrowserBack">
<Button HotKey="BrowserForward">

Workaround using a pointer event on the toplevel below.
You can also use class handlers for app-wide reach (PointerReleasedEvent.AddClassHandler<TopLevel>(OnPointerReleased);)

public MyComponent()
{
	InitializeComponent();

	TopLevel? topLevel = null;
	AttachedToVisualTree += delegate
	{
		topLevel = TopLevel.GetTopLevel(this)!;
		topLevel.PointerReleased += OnPointerReleased;
	};
	DetachedFromVisualTree += delegate
	{
		topLevel?.PointerReleased -= OnPointerReleased;
	};
}

private void OnPointerReleased(object? sender, PointerReleasedEventArgs args)
{
	if (args.InitialPressMouseButton == MouseButton.XButton1)
	{
		BackClicked();
	}
	else if (args.InitialPressMouseButton == MouseButton.XButton2)
	{
		ForwardClicked();
	}
}
