I don't think any screen readers use IAccessibleEditableText.
When we were implementing it for Eclipse, the only test tools we had were 
inspector-type tools.
(Maybe GOK uses some of it - Peter, do you know?)

I believe the intent was that it could be useful for speech recognition 
systems.
As I understand it, speech reco systems are currently masters at stuffing 
characters onto the event queue to simulate typing.
Maybe this is less efficient and/or maybe error prone - I don't know.

Jamie, I like that idea. I have always had the feeling that the clipboard 
operations didn't belong on IAccessibleEditableText. Having them on 
IAccessibleAction makes more sense to me, too, because as others have 
pointed out, clipboard operations are not just for text objects. And I 
agree that these actions do merit some kind of quick access mechanism - 
either they can have their own method names or predefined action 
constants. They can operate on the current selection, thus removing the 
need for those pesky offset parameters , and allowing 
multi-selection-capable applications to define their own semantics for 
clipboard "actions". Also, as Malte pointed out, paste and pasteSpecial 
are boolean in nature, so they can be 2 actions. The clipboard format for 
pasteSpecial can (I think?) be handled on the application's side, i.e. ask 
the user whether they want to paste html or rtf or plain text, etc 
(depending on what is on the clipboard).

[Accessibility-ia2] reorder events issue

2011-06-29 Thread Pete Brunet 
Alex, I don't remember the founding discussions for the reorder events
issue.  Please update the proposal wiki page with a link to that
discussion.  Thanks, Pete

 Hi, Jamie. I missed Mick suggestion on the list. It's sounds
 reasonable and I agree we should try it before getting new API for
 this since the issue is mostly about events.

 Thank you.
 Alex.

 Hi.

 Nice work; good to get the discussion going. :)

 I still don't see a need for this registry API. Why not just use
 IsWinEventHookInstalled(), as Mick suggested on the IA2 list?

 Thanks.

 Jamie

 feedback
 here and feel free to edit the wiki.

 Thank you.
