Detect when user has switched editing modes in CKEditor

Question

In CKEditor, is there an event that can be bound to which fires when the user switches between the WYSIWYG view and the source view?

If not, I need to enable/disable some other controls on the page when the view changes; what's my best strategy?

Answer 1

I'm still unable to find any documentation, but after poking around the internals of a CKEditor instance, I was able to find the event I'm looking for:

instance.on('mode', function() {
     // Code to execute when the user switches editing modes
}

Easy enough. The event fires once when the editor is initialized and again any time the source command is activated (either through instance.execCommand(...) or the user clicking a Source toolbar button).
