How to open new command window?

I have some codes that I have saved in comand window and I want to create a new command window. So that I don't lose my code. Please help me.

"I have some codes that I have saved in comand window.."

The command window does not save any code. It does allow you to enter statements and see displayed results:

You can launch a new Matlab session with its own command window, but the way you are going about saving work is very peculiar. Most people would save their work to a .m or a .mlx file

If you look closely you will understand that it is indeed untitled.m file.

But you asked about the command window. Did you mean the editor window? I see no open editor windows in your screenshot.

Lower left corner, there is an untitled.m editor session, which appears to be showing an empty file.

Copying out of the command history and pasting into the editor window would permit creating a script that had the commands.

https://www.mathworks.com/matlabcentral/fileexchange/48593-save-entire-command-history-updated-fast can be used to save the command history.

https://www.mathworks.com/matlabcentral/answers/97504-how-can-i-access-the-saved-command-history-in-matlab talks about where MATLAB saves the command history.

If you up-arrow at the beginning of a command line, the command history will be shown. You can click and drag your selection to select several lines, and you can control-C (command-C on Mac) to copy those commands into your paste buffer.
