Re: [SUE-list] SUE under Ubuntu 10.4

[Ramona B. <bu...@it...>]

Hello Bernhard,

sorry, but seems I can't help you there. SUE does not tell me anything 
about an "Indicator Applet" in my Upper Edge Panel. I have one Tab 
between the "Network Manager" and the Date where I don't have any 
output. I can enter the elements in there with the arrow keys and leave 
the area with escape. But the screenreader does not give me any feedback 
there. Orca at least tells me, that it is a menulist. After I entered 
this particular area I also had a problem with using my keyboard. It 
seems to me that there are still some gnome bugs here?


I promised on Friday to give a few more information to the problem, with 
the alt+ctrl+tab key combination.
GNOME can run with two different window manager. That is the program 
that draws the windows on your desktop. The window managers under gnome 
are Metacity and Compiz. The key combination alt+ctrl+tab is a 
combination from Metacity. Compiz does not have a key combination for 
moving between the desktop and the panels with the keyboard.

You change from one window manager to the other in the "Appearance" 
dialog, that can be found in the Upper Edge Panel menu 
System/Preferences/Appearance
There choose the page tab "Visual Effects" On this page tab you can 
choose between the Options "None", "Normal" and "Extra". "None" uses 
Metacity and the other two use Compiz.

If you want to use Compiz you can change some keyboard settings in the 
Compiz Settings Manager. You can get Compiz to do the same with 
alt+ctrl+tab like Metacity does.
First install the "CompizConfig Settings Manager":
   sudo apt-get install compizconfig-settings-manager
Then open the Settings Manager. It can be found in the Upper Edge Panel 
menu System/Preferences/CompizConfig Settings Manager
Here look for the category "Window Management" and then for the plugin 
"Static Application Switcher". In the plugin there is a page tab called 
"Tastenkombination" (in english maybe "key combinations"?)
Here you can set a key combination for "Next Panel" and "Prev Panel". 
You will find two such settings on the page. The first is always for 
mouse use and the second for the keyboard.

Greetings,
Ramona

Then I have some important icons like "Firefox", "Network Manager", "Ubuntu Help", then I come to the Indicator Applets. I take the second one, called "Indicator Applet Session". Well, it looks to me like a kind of tree view - I may open branches with the right arrow, and I may go down within a branch with the down arrow, perhaps I even may close a branch with the left arrow, but I may never leave this Indicator applet again - it seems "absorbing" to me. In particular, I cannot go back to the Desktop with alt-control-tab, and also my beloved alt-F1 to access the Aplicatins menu doesn't work anymore.
