How to handle Key + Mouse Wheel simultaneously?

Question

My camera code now looks like this:

     private void Update()
     {
         float zoomDelta = Input.GetAxis("Mouse ScrollWheel");
         if(zoomDelta != 0f)
         {
             AdjustZoom(zoomDelta);
         }
     }

I want to bind camera zoom to Ctrl + Wheel because I want to bind a wheel to brush size in my map editor. The problem is both Input.GetAxis(string) and Input.GetKeyDown(KeyCode) don't work simultaneoulsy.

Turns out should use Input.GetKey(KeyCode) instead of Input.GetKeyDown(KeyCode). Final code:

     private void Update()
     {
         if (Input.GetKey(KeyCode.LeftControl))
         {
             float zoomDelta = Input.GetAxis("Mouse ScrollWheel");
             if (zoomDelta != 0f)
             {
                 AdjustZoom(zoomDelta);
             }
         }
     }
