I had a good time implementing your first request tonight.

Added ModifiedAcceptsReturnBehavior.cs:

```auto
using System.Linq;
using System.Windows;
using System.Windows.Automation.Peers;
using System.Windows.Automation.Provider;
using System.Windows.Controls;

namespace Quantum.Client.Windows
{
    public static class ModifiedAcceptsReturnBehavior
    {
        public static readonly DependencyProperty IsEnabledProperty =
            DependencyProperty.RegisterAttached("IsEnabled", typeof(bool), typeof(ModifiedAcceptsReturnBehavior), new PropertyMetadata(false, OnIsEnabledChanged));

        public static bool GetIsEnabled(DependencyObject obj) => (bool)obj.GetValue(IsEnabledProperty);

        static void OnIsEnabledChanged(object sender, DependencyPropertyChangedEventArgs e)
        {
            if (e.Property == IsEnabledProperty && sender is TextBox textBox && e.NewValue is bool newValue)
            {
                if (newValue)
                    textBox.PreviewKeyDown += PreviewKeyDown;
                else
                    textBox.PreviewKeyDown -= PreviewKeyDown;
            }
        }

        private static void PreviewKeyDown(object sender, System.Windows.Input.KeyEventArgs e)
        {
            if ((App.Configuration?.EnterConfirmsDialogsInMultilineTextboxes ?? true) &&
                sender is TextBox textBox &&
                textBox.AcceptsReturn &&
                e.Key == System.Windows.Input.Key.Enter &&
                !System.Windows.Input.Keyboard.IsKeyDown(System.Windows.Input.Key.LeftCtrl) &&
                !System.Windows.Input.Keyboard.IsKeyDown(System.Windows.Input.Key.RightCtrl) &&
                !System.Windows.Input.Keyboard.IsKeyDown(System.Windows.Input.Key.LeftAlt) &&
                !System.Windows.Input.Keyboard.IsKeyDown(System.Windows.Input.Key.RightAlt) &&
                !System.Windows.Input.Keyboard.IsKeyDown(System.Windows.Input.Key.LeftShift) &&
                !System.Windows.Input.Keyboard.IsKeyDown(System.Windows.Input.Key.RightShift) &&
                Window.GetWindow(textBox).FindVisualChildren<Button>().FirstOrDefault(b => b.IsDefault) is Button defaultButton &&
                new ButtonAutomationPeer(defaultButton).GetPattern(PatternInterface.Invoke) is IInvokeProvider defaultButtonInvokeProvider)
            {
                defaultButtonInvokeProvider.Invoke();
                e.Handled = true;
            }
        }

        public static void SetIsEnabled(DependencyObject obj, bool value) => obj.SetValue(IsEnabledProperty, value);
    }
}

```

Invoked the new guy in the default text box style:

```auto
<Style x:Key="AppTextBoxStyle" TargetType="{x:Type TextBox}" BasedOn="{StaticResource TextBoxStyle}">
    <!-- other stuff I didn't paste in here -->
    <Setter Property="local:ModifiedAcceptsReturnBehavior.IsEnabled" Value="True" />
</Style>

```

That’s right, bruh. Took less than fifteen minutes to implement. Still got it.

Ahh, let’s see how hard _that_ would be…
