If you're using threejs, I think you might be able to set up an eventListener on the keyboard, and basically say "when shift and UP are pressed, increment the camera.position.z+10".

Here's a little code to get you started. It listens to the keyboard, console logs what key it was, and moves the camera along the Z access by 10:

    function setupKeyLogger() {
        document.onkeydown = function (e) {
            console.log(e);
            camera.position.z+10
        }
    }
