58987 - No keyboard access for tab control

Status: VERIFIED FIXED

(Core :: DOM: UI Events & Focus Handling, defect, P3)

Description

[Aaron Leventhal]

For example, go to the Cookie Manager under Tasks - Privacy and Security -
Cookie Manager - View stored cookies. There is no way to keyboard from tab to
tab. In windows this is done with Control-Tab and Shift-Control-Tab, but this
may not work for Unix users. On my KDE system, Control Tab moves through the
desktops.

However, there needs to be some way to move through the items via the keyboard.

As Sarah and I discovered, tabbed dialog box navigation is different in Modern
and Classic.
In modern, it doesn't work at all.
In classic, you have to click on a tab widget first, then you can arrow through
them.

I see this too on Win98, setting all/all.

On Win Classic and Win98, you can also Tab through the tabs, which isn't right 
(you should only be able to arrow through them).

Chaning the qa contact on these bugs to me. MPT will be moving to the 
owner of this component shortly. I would like to thank him for all his hard 
work as he moves roles in mozilla.org...Yada, Yada, Yada...

So let's use (Shift+)Control+Tab. Apart from Alt+Tab, we can't avoid every 
possible modifier+specialkey combo just because it might be taken up by
over-eager window managers. That's not reasonable.

Reassigning to Bryner -- I think he has a bug on this already.

Please use www.mozilla.org/projects/ui/accessibility/mozkeyintro.html, and the 
associated keys cross-reference list, when suggesting keystrokes.

Ctrl+Tab is currently being taken by pane/frame navigation.

If we also use it for tabbed dialog navigation, be aware that would need to 
override frame navigation. Therefore, once a user navigated into the sidebar, 
they wouldn't be able to get out.

That's what the cross-reference is for, so we don't get into these keyboard 
conflict situations.

Aaron, that is not correct.

Control+Tab is not `taken' by frame/pane navigation, because there are no 
tabbed dialogs in Mozilla which also use frames (and there never will be, on my 
watch). <http://mozilla.org/projects/ui/accessibility/mozkeylist.html> clearly 
suggests Control+Tab for navigating between tabbed dialogs.

And once a user navigated into the sidebar, they would so be able to get out 
again, by typing Control+Tab again. The sidebar does not use a tab control, and
<http://mozilla.org/projects/ui/accessibility/mozkeylist.html> clearly suggests
(Shift+)accel+PgUp/PgDown for navigating between sidebar panels. (That keyboard 
combo is far from ideal, but the main point is that it's not Control+Tab.)

In future, if you disagree with your own keyboard spec, please discuss your 
disagreement in the relevant newsgroups before using it as an argument in 
Bugzilla. Thanks!

aaronl -- I did go ahead and implement ctrl+[shift+]tab as a shortcut for
changing tabs.  If you think that behavior isn't correct, please file a new bug.

This is still a problem.
See bug 78256
