KDE/ QT/ Plasma accessibility contributions

Howdy list,

My name is chrys. I m a visual impaired guy from germany. I m new to  
this list.
Since Gnome gets more and more crippled i decide to change to KDE/ Plasma.
And it was one of best decisions I did. Plasma is awsome and i wont  
miss it now (lol).
I use KWins zoom plugin.

My girlfrind is blind. She currently switched to Mate for the same  
reason like me. Mate is pretty accessible. But there are a lot of  
stuff missing what we would suspect from an modern desktop (search in  
menu and those stuff).
Plasma has all that. So i decide to try plasma using Orca.
My results: Its very slow, unstable and often hard to navigate. But it  
worked at all! thats more that i was suspecting. What tells me that  
the plasma shell already exposes the needed information to the at-spi  
(cool).
Impressed by that results, I want start fixing up stuff for KDE/  
Plasma/ QT a11y to make work for her (and ohters) one day.
So i read
https://community.kde.org/Get_Involved#Accessibility
and
https://techbase.kde.org/Development/Tutorials/Accessibility
what brings me to the point to say hello here in the list :).

Sadly information is very rare in a11y stuff (not only for KDE). Thats  
why i want to find others who maybe already have knowledge to Mentor  
me or wants to work together with me to raise the motivation and fun  
:). on my way to get touched with that.
So:
1. Is there someone out there who wants to join my effort?
2. Is there someone out there who can Mentor me a bit for my first steps?
3. Is there an effort what already exists what i can maybe join?

cheers chrys
