This is a script I ask ChatGPT to create it. It copies track camera key from previous frame to the current frame that the cursor is on. You can use it and modify it as you like.
It is not different from selecting the track camer, then click once on the canvas to create the track camera key, just this time we only need to click on the tool icon. More quicker, we can set the custom shortcut key.
