add code for event listener for keypress in ckeditor

Question

I need to add an event listener for keypress after the CKEditor is loaded. The code is something like:

CKEDITOR.instances.editor1.document.on('key', function(event) {
    /* instructions   */
});

Any idea where can I add the code for that? In which file or in what way?

Answer 1

Code to archive it is something like this:

CKEDITOR.on('instanceCreated', function(e) {
        e.editor.on('contentDom', function() {
            e.editor.document.on('keyup', function(event) {
                // keyup event in ckeditor
            }
        );
    });
}); 

Edit - 2014 - Since this answer is still getting some upvotes, i felt it would be fair to point out, that it was meant for CKEditor in version 3.x. With the version 4.x there is a change event, which will trigger not only on key events but also after pasting, undo, redo etc.

In code its something like this:

CKEDITOR.on('instanceCreated', function(e) {
    e.editor.on('change', function (event) {
        // change event in CKEditor 4.x
    });
});
