I'm assuming you're a designer and what you're wondering about in the bottom left corner of the screen are shortcuts to various commands, many of which I defined myself other than what's in the system and what's displayed in the corner. The bottom left is in the editing process. I prepared the images beforehand and used Wondershare Filmora to manage them. I'm not sure if my answer will resonate with you or not. If it's not correct, I have to ask you to explain the question again.😊
