A little introduction and a question about enabling certain accessibility options

Hello everyone,


My name's Francisco, and I'm a blind highschool kid who just recently 
started using Linux.

I first went with Ubuntu, switched to Arch, and then, came across 
Fedora, which I'm using right now to send this email for example.

I have to admit, I'm finding the experience both with the OS and Gnome 
pretty good so far, but there's one little question that I'd like 
answered if possible.

In the home directory of my Fedora installation, there doesn't seem to 
exist a .xinitrc file, which, by a guide i gathered from Arch, has some 
accessibility options set to enabled or disabled.

Well, because of that, i believe, google chrome, signal, the messaging 
app, and other apps that worked perfectly, and talked, with Orca, yeah, 
i forgot, i use orca cause I'm blind, are not working here, or so i 
think, cause so I gather from my experiences.

The accessibility options are


export GTK_MODULES=gail:atk-bridge
export GNOME_ACCESSIBILITY=1
export QT_ACCESSIBILITY=1
export QT_LINUX_ACCESSIBILITY_ALWAYS_ON=1

Well, my question is, is there a way to enable those, or to make sure 
they are enabled, creating a xinitrc file, or adding those options to 
somewhere?

I'm not that experienced with Linux, but I'm trying to use it as a day 
to day work machine, and i can, but, this thing about these 
accessibility options being enabled or not is bothering me, especially 
because I can't seem to be able to use Chrome, which is the browser i 
always use.

Than you for any answer.

Best regards.

Francisco.

P.S. The Fedora list directed me here.
