[orca-list] Ubuntu 10.04 and better accessibility

[Petr Bláha <hammet pb seznam cz>]

Hello,
i just tried live DVD of the new Ubuntu 14.04 Trusty Tahr,
unity version seems to be much more accessible here,
only issue i have noticed is that when i switch windows by pressing alt + tab, this feature behaves little 
strange with orca,
Wien i press alt + tab for the first time orca announces only “swhiching window tool” but when i press it 
twice, the second window in order is spoken properly.
Session manager is accessible which is great improvement as well,
When i press the super key unity seems to be accessible too, but when i select for example applications and 
then installed, no list of apps appears, maybe it is necessary to press any key to view contend of folder - 
not sure about this.
