Overriding ctrl-= in javascript
<p>I'm building a basic online graphics editor, and I want to override the browser zoom, when the user hits Ctrl-= (that is the ctrl key followed by the = key) I want the canvas to get larger (I'll handle this via an event), but any attempt to capture this key combination causes my event to fire and then the page to resize anyway. How do I avoid the browser continuing to resize my browser?</p>

<p>I tried this with other keycodes, ctrl-s does not fire the browser save if I override it for example.</p>

<p>I realise this isn't an amazing usability idea generally, but in the given context of a design application I believe it to be ok.</p>

<p>Thanks!</p>
