I am using the Message dijit in place of javascript alert() and confirm() to match the style of WAB. However, it is not possible to use key events to select the buttons, which is not ideal.
Looking at the base class (Popup) I see that there is a property called key which seems to correspond to a member of dojo/keys for this very purpose. Sadly, all the relevant code is commented out.
Has this functionality been deprecated, or can we expect to see it implemented in a future release?
