Question

Efficient handling of keyboard shortcuts in JavaScript for maximum functionality

What is the most effective method for implementing a global keyboard shortcut manager for a web application using JavaScript? Which events should be targeted and where should the event handlers be connected?

I am looking to replicate the functionality seen in Gmail, which supports single key shortcuts as well as those with modifier keys such as Ctrl + B. The solution should be compatible with IE 6 and modern browsers.

I have access to the Prototype framework but not jQuery, so please refrain from providing jQuery-specific responses!

To enhance user experience, I would suggest attaching onKeyUp events directly to the document.body element. Within the event handler function, utilize the Element.fire method to trigger a custom event. This approach not only increases flexibility by separating the event handler from the specific action, but also allows for reuse of the custom event handler across different types of interactions such as button clicks.

$(document.body).observe("keyup", function() {
    if(/* condition for key + modifier match */) {
        $(document.body).fire("myapp:mycoolevent");
    }
});

$(document.body).observe("myapp:mycoolevent", function() {
    // Handle the custom event.
});

For implementing the same event with a button click:

$(button).observe("click", function() {
    $(document.body).fire("myapp:mycoolevent");
});

Regarding modifier keys, you may find helpful information in this resource (although dated, it still offers relevant insights).
