Bug#820911: installation-report: Accessibility for visual impaired is broken,, High-Contrast Theme is no longer activated by shortcut

[Alex ARNAUD <alexarnaud@hypra.fr>]

Dear all :),

The issue still appears in the Debian Installer Stretch Alpha 8 (on EFI).

I don't know how to fix this issue myself so I think at this time we 
have two options :
- Change the Debian installation guide to help visual-impaired to
activate the ncurse or graphical high-contrast theme.
I'm not able to write it myself because the contrast of the first screen
makes it completely unreadable for me.
- Resolve the issue to provide the same easy steps as describe here : 
https://www.debian.org/releases/jessie/amd64/ch05s02.html.en#idp71552032

This issue also affects blind people who have non-USB braille displays 
(because the device is not auto-detected).

I'm available on IRC (nickname alexarnaud) or by mail to discuss what is 
for you the best way for making the Debian Installer accessible
for everybody.

Best regards.
