New feature suggestion, adding keyboard shortcut feature [muscore.com]

I hope you can add a great feature: my daughter loves playing the piano on your website muscore.com, and sometimes she needs to practice repeatedly. Could you add a keyboard shortcut feature so that pressing the left or right arrow keys can rewind or forward a section of the music? like youtube video player . This would make it convenient for her to practice certain pieces repeatedly. Looking forward to your response.
