title: Override browsers CTRL+(WHEEL)SCROLL with javascript
body: <p>In most browsers on linux, <kbd>CTRL</kbd>+(WHEEL)SCROLL allows the user to zoom in and out of the page by enlarging or shrinking the size of all elements. Now I want to override this behaviour and get <kbd>CTRL</kbd>+WHEEL to zoom into an SVG element I have by applying affine transformations.</p>
  
  <p>Is this possible? Specifically, is it possible to catch this keyboard/mouse event as well as suppressing the browser's default behaviour?</p>
