Silverlight shortcut and default browser shortcut options are available for users to navigate more efficiently

Looking to implement custom keyboard shortcuts in my app, I added a keydown event handler as shown below:

Application.Current.RootVisual.AddHandler(UIElement.KeyDownEvent, new KeyEventHandler(HandleKeyDown), true);

However, an issue arises with certain shortcuts like Ctrl+S and Ctrl+T, which trigger the browser's default actions.

I attempted to disable these browser shortcuts from the aspx file containing the Silverlight using JavaScript:

onkeydown = function(e) {
    if (e.ctrlKey && e.keyCode == 's'.charCodeAt(0)) {
        e.preventDefault();
    }
};

Does anyone have any suggestions on how to disable the default browser shortcuts and use custom ones instead?

Sure thing, give this jquery plugin a shot

https://github.com/jeresig/jquery.hotkeys

Before you dive in, here's something to note:

When it comes to handling keyboard shortcuts, Firefox is the most lenient by allowing you to capture all shortcuts, even those that are pre-defined in the browser like Ctrl-t for opening a new tab or Ctrl-a for selecting all text. You can send these shortcuts back to the browser by returning true in your event handler.

On the other hand, browsers like IE may let you handle built-in shortcuts but will execute their functionality after your code runs. Meanwhile, Opera and Safari don't pass these types of events to the Document Object Model (DOM) at all.

Therefore, if you bind Ctrl-Q or Alt-F4 and find your Safari/Opera window suddenly closed, don't be caught off guard.

I had success using this plugin on Chrome, but in Firefox both the JavaScript event and the browser event were triggered simultaneously.
