I need a clear example of how to create a key listener, or whatever code will help solve my problem.

I'm making an Oregon trail style game, and I need a something to pause the game when the user hits a key and open a menu. I haven't been in MatLab for long, and I could really use some help. All of the articles I found haven't made much sense and either didn't have any example codes or if they did have code it was really complicated.

Do you want to stop the execution, when the user opens a menu, or should the menu be opened, when the user hits a key?
