(C#) How to display bold text all line/letter in Console.Write()?

I'm trying to display the shortcut key inside a word in a Console Aplication like "expert", "save all" but I can't find any solution...

Console.ForegroundColor = ConsoleColor.Cyan;
Console.WriteLine("Loading Predefinitions...");
[...]
Console.ResetColor();
Console.WriteLine("Options: (L)Load (E)Edit (S)Save (A)Save All (R)Reset");

Have any way to do this?
