The Facebook send button doesn’t seem to be keyboard accessible. When I tab to the send button, there is no indication that the button is focused, and hitting enter doesn’t have the same affect as clicking the button.
Is there a way to make the Facebook send button keyboard accessible?
PS. the tweet button, which seems to be done in a similar way doesn’t have the same problem.
Log a bug with Facebook. The content of the send button is inside an iframe so you realistically won’t have access to make changes to it due to cross-domain restrictions.
