370164 - no longer can click on tab and use down arrow to scroll page

Status: RESOLVED WONTFIX

(SeaMonkey :: UI Design, defect)

Description

[Daniel B.]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.2pre) Gecko/20070111 SeaMonkey/1.1
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.2pre) Gecko/20070111 SeaMonkey/1.1

The "feature" of having the up, down, left, and right arrow keys 
switch tabs has broken the long-standing ability to click on a tab 
and then use the arrows to scroll the page.

Normally (e.g., in an untabbed window, and before 1.1) one can use 
the four arrow keys to scroll the web page up and down and left and 
right in the display pane.

Now, if you click on a tab in a tabbed window, and then press an
arrow key to try to scroll around, Seamonkey switches to a 
different tab.

To scroll the page with the arrow keys, you have to find some
inactive area in the page to click on and then click there (to take
focus from the tab label), and only then can you use the arrow
keys to scroll around.


Seamonkey should use some other keys or key combinations to 
switch tabs.




Reproducible: Sometimes

Steps to Reproduce:
(It happens every time clicking on the tab gives focus to the tab label,
but a couple of times I clicked on the tab, the tab label didn't get
focus.)

1. In one tab, open a page tall or wide enough to enable scrollbars.
2. Starting from another tab, click on the first tab.
3. Press arrow keys to try scrolling around in the displayed page.

Actual Results:  
Seamonkey switched to a different tab.

Expected Results:  
It should have scrolled around in the page.

(Alternatively, there should have been an easy way to take focus from
the tab label (certainly easier than having to scan the displayed web
page to find an inert area on which to click).)

Can you reproduce with SeaMonkey v1.1.9 ?

Yes, but it's now clear that the problem depends on more things. 

Whether arrow keys scroll the content after you clicking on a tab depends 
on whether (inter-window) focus has shifted to another window and back since 
(intra-window?) focus has been given to the content display pane:

1. In one tab, open a page tall or wide enough to enable scrolling.

2.1 Starting from another tab, click on the first tab.
2.2 Press arrow keys (to try scrolling around in the displayed page).
2.3 Notice that the arrow keys work right (they scroll the content around).

3.1 * Click in another window to take focus from the SeaMonkey window and 
    then click in the SeaMonkey window to given focus back.
3.2 Press arrow keys.
3.3 Notice that arrow keys still scroll.

4.1 Click on the selected tab (or any tab).
4.2 Press arrow keys.
4.3 * Notice that arrow keys now do NOT scroll but change tabs.

5.1 * Click somewhere neutral in the content or drag to select some text.
5.2 Press arrow keys.
5.3 Notice that arrow keys now do scroll.

6.1 Click on the selected tab (or any tab).
6.2 Press arrow keys.
6.3 * Notice that arrow keys STILL scroll.  (That is, after clicking on a 
    tab, this time they scroll, but in 4.x they didn't.  The difference is
    the history of focus changes.)

(Obviously, how arrow keys work after you click on a tab probably should not 
depend on whether you have switched to another window since you have given
focus to the content pane in the browser window.)

I confirm that when clicking on a tab does not change tabs (e.g. after clicking the current tab), left-right arrows change tabs and up-down arrows do not scroll the page.

This might be intended behaviour however.

I believe that's correct behaviour for accessibility reasons.
