Thank you so much for teaching me from the beginning, a top developer. I'm watching it well. I will continue to purchase lectures and learn from them in the future. However, I've only used Eclipse for 4~5 years, but I'm learning IntelliJ for the first time through this lecture and I'm having some trouble with shortcuts. I can just search for it and move on, but for students who are just starting out in development, even if there's a stop button, I think it would be helpful for students to go on and explain the shortcuts. Anyway, thank you for the great lecture.
