Hello! @ferdinand ,@Cairyn Thank you for politely teaching me! I was able to solve the title problem. I will use an external editor. I also understood loading plugins! I was restarting the software many times. I have a new question, but if you study a little more and don't solve it, let me ask you another thread. I'm really thankful to you!
