Keyboard shortcuts - .NET MAUI

In MAUI, there is no cross platform way to achieve setting a keyboard shortcut. But, you can listen for keypresses by overriding the default MainActivity.KeyUp method for Android, and for iOS by setting up a UIKeyCommand inside the default AppDelegate.

Android implementation:

[Activity(
    Theme = "@style/Maui.SplashTheme", 
    MainLauncher = true, 
    LaunchMode = LaunchMode.SingleTop, 
    ConfigurationChanges = ConfigChanges.ScreenSize | 
                           ConfigChanges.Orientation | 
                           ConfigChanges.UiMode | 
                           ConfigChanges.ScreenLayout | 
                           ConfigChanges.SmallestScreenSize | 
                           ConfigChanges.Density
)]
public class MainActivity : MauiAppCompatActivity
{
    public override bool OnKeyUp([GeneratedEnum] Keycode keyCode, KeyEvent? e)
    {
        if (keyCode == Keycode.F && e.IsCtrlPressed)
        {
            //Apply any logic

            return true;
        }

        return base.OnKeyUp(keyCode, e);
    }
}

iOS implementation:

[Register("AppDelegate")]
public class AppDelegate : MauiUIApplicationDelegate
{
    public UIKeyCommand FKeyCommand = UIKeyCommand.Create(
      new NSString("f"), 
      UIKeyModifierFlags.Control, 
      new ObjCRuntime.Selector("Action:")
    );

    protected override MauiApp CreateMauiApp() => MauiProgram.CreateMauiApp();

    public override UIKeyCommand[] KeyCommands
        => new[] { FKeyCommand };

    [Export("Action:")]
    private void Excute(UIKeyCommand keyCommand)
    {
        //Apply any logic
    }
}
