Why can't we say if the caret should move logically or visually forward? We can implement it either way regardless of the underlying platform, right? -----Original Message----- From: Ryosuke Niwa [mailto:rniwa@apple.com] Sent: Monday, December 8, 2014 3:21 PM To: Ben Peters Cc: public-editing-tf Subject: Re: Default Caret and Selection Positioning Spec? We can't do that because it's more of a UI/UX problem that depends on the underlying platform.
