Edit, let's do this with an enum - full source

using System;  
using System.Collections.Generic;  
using System.ComponentModel;  
using System.Diagnostics;  
using System.Windows.Forms;  
using EnumDescriptions.Classes;  
  
namespace EnumDescriptions  
{  
    public partial class Form2 : Form  
    {  
        public Form2()  
        {  
            InitializeComponent();  
  
            List<KeyValuePair<string, Enum>> result =  
                EnumHelper.GetItemsAsDictionary<WindowKeys>();  
  
            comboBox1.DisplayMember = "Key";  
            comboBox1.ValueMember = "Value";  
            comboBox1.DataSource = result;  
        }  
  
        private void button1_Click(object sender, EventArgs e)  
        {  
            MessageBox.Show(comboBox1.SelectedValue.ToString());  
        }  
    }  
  
    public enum WindowKeys  
    {  
        [Description("Windows + M")]  
        M = 1,  
        [Description("Windows + A")]  
        A = 2  
    }  
}  
  

Core code

public class EnumHelper  
{  
    public static List<KeyValuePair<string, Enum>> GetItemsAsDictionary<T>() =>  
        Enum.GetValues(typeof(T)).Cast<T>()  
            .Cast<Enum>()  
            .Select(value => new KeyValuePair<string, Enum>(  
                (Attribute.GetCustomAttribute(value.GetType().GetField(value.ToString())!,  
                    typeof(DescriptionAttribute)) as DescriptionAttribute)!.Description, value))  
            .ToList();  
  
}
