I'm aware that you can type international characters in two ways in Lion and Mountain Lion: You can either press and hold the key and choose the character, or you can press Alt + Key followed by another key to type accents on characters. However, I am unable to find a way to type these two characters: ű, ő (u with two accents, and o with two accents). These are Hungarian characters by the way, and they are used very commonly in Hungarian, and it would be great if there would be a way for me to type them quickly and easily. Does anyone know if there is a way to add characters to the menu that appears when you press and hold a key? Do these change when you change your language, or keyboard settings, etc ? Thanks!
