How to swap Control to Command in cool-retro-term on macOS?

[aldjsflkdslfkdhsfdhsfkhssfhs77]

At first, I thought that this terminal doesn't support shortcuts on macOS, but it turned out instead of Command + "..." you should use Control + "...". Also, even when I use Control, I couldn't replicate all standard commands that you can find in the default Terminal. Is there a way to directly change the shortcuts by modifying some files or do I need to create a workaround for this problem?
