[Yuedong Du <yuedong du sun com>]

sorry for resend because my typo of mail address.

Hi Hackers,

Our group will start  a project that made evolution more accessible.
 Keyboard navigation is part of the project.

Attached is our proposal, comments are welcome.  The proposal try to
attack two parts that keyboard navigation
are weak or vacant, gtkhtml mail reader can calendar. While in other
parts keyboard navigation mostly work, and
we think it can be resolved by bugfix.


Thanks

Title: proposed keyboard nav for evolution mail

Proposed Keyboard Navigation for Evolution Mail Reader and Calendar

- By bolian yin sun com and yuedong du sun com

1.Introduction

     Evolution already support lot of keyboard access. The document is not
 intended  to include all of them,
     we focus on navigation in mail reader(gtkhtml) and calendar. Because 
these   two parts are largely absent.
     
     For other parts that do not follow gnome keyboard navigation rules,
we  have  file a meta bug
     at http://bugzilla.ximian.com/show_bug.cgi?id=42070.

2.1 Evolution Mail Reader (Gtkhtml)

2.1.1 Current Status

     When you read a mail with evolution, you can page up/down or move line 
 up/down  with arrow. This is because gtkhtml
     inherited from Gtklayout widget. And it is enough for a normal user. 
But  to be accessible, the mail reader need
     full support of cursor. Thus, accessive application, e.g. screen reader, 
  can trace the cursor change in a mail,
     and get ATK object corresponding to current html object.
     
     Currently, cursor seems implemented just for edit. So we need to enhance
keyboard navigation and port  cursor  
from editor to reader.
