It's with short keys as all other serviceability, they do not work anymore. Then again, DA has never bothered with making the size available for those with disabilities. Before the eclipse downgrade you could make adequate use of the site, even if you had a disability, today you are all left behind. For instance a reader does not find the buttons for submission.
I think it's rather the case that the DA developer don't know what short keys are, or to develope code that manages these things. After all they don't seem to know the first thing about UX. Just the way the comment boxes works since the eclipse downgrade is a disgrace.
