[orca-list] How to make Ubuntu 12.10 accessible?

[Petr Bláha <hammet pb seznam cz>]

Hi list,
I have installed the new Ubuntu 12.10 yesterday and i can use it with 
some restrictions. The biggest problem is, that i am not able to go 
through dash.
Switching between windows by pressing alt+tab is also quite difficult, 
even it is accessible.
So i would like to ask you whether there is some way how to make 12.10 
more accessible? Or may i try to install 12.10 with XFCE or KDE 
interface? Or the best choice is to use 12.04 till the accessibility 
will be better in the latest release?
Thank you for your answers.
