How to Check if jQuery .keydown() has any other keys pressed or not?

I am using WordPress jQuery to build some shortcuts for my site.

It works as intended, however it doesn't stop when other keys are pressed.

For example, if I press, f it performs the necessary task. But if I press CTRL + f then also it does the task.

Infact, I tried, other keys like f and p and that too worked.

I want it to only work on the specific key. Incase of any other key press, it should not run. It should run on clicking f, but NOT run on CTRL + f.

I tested this on Chrome 92.0.4515.159 and Chrome Beta Version 94.0.4606.31 on Windows 7 and 8.

    jQuery(window).keydown(function(e) {
        if( e.which === 27){
            jQuery('.SearchCreationsClose').click();
        }
        if(e.key == "f"){
            e.preventDefault();
            jQuery('.SearchCreationsIcon').click();
        }
    });
