How to enter the name of a horse in Zelda

Please, search on Baidu yourself. I personally researched a simple method: first set the control to the keyboard, and then only set the four keys A, B, and - to keys other than the letter keys of the keyboard, and then By using the keyboard to talk, you can enter the name directly on the keyboard. After entering the name, press and hold the key you set and then press the Enter key on the keyboard to enter the name.
