If a message is displayed in the message window and a scrollbar appears next to the message usage of the scrollbar should change the focus so the arrowkeys of the keyboard can be used to further navigate through the message. Instead the focus remains where it was, usually the window above where the messages are listed. Hence usage of the arrowkeys changes the message on display. If one clicks on the rest of the messagewindow where the message itself is on display then the focus is set correctly.

So, we need to move focus from Thread pane to Message Body pane and activate arrows keys - after clicking on a scrollbar from Message Body.

Agree. Clicking on a message pane scrollbar should give the message pane focus.

Updating multiple bugs. This is a valid UI issue. Would be nice to have it fixed if time allows.

I don't think this is an accessibility bug because someone whose using the keyboard only would have tabbed to the message pane and that works fine. This also doesn't appear to be a mail bug. If I go to the browser and put focus in the sidebar (say on my history list) and then click the scrollbar for this bug report and then use the arrow keys, the history list selection changes, not the page. It looks like scrollbars don't change focus to the area they control. reassigning to XPToolkit but this may not be the correct component.

-> future, unless one of the new cc's wants to do this

Tested in Windows Explorer, if you clicked on an folder listed in the left pane, then dragged the scroll bar in the right pane to navigate. Here, you pressed Up/Down arrow, the focus still remained in the left pane. So I don't think this is a bug, it's a feature.

Dupe of bug 9086?
