[BRLTTY] Android: Sending control- or alt characters using BrlTTY keyboard

[henk.abma at gmail.com]

Hi,

I was hoping it would be possible to use the TalkBack keyboard commands from
a braille display. In order to do so, one would for example need to be able
to send alt+spacebar (for the global context menu) from a braille display. 
Functionality like this could also be helpful when trying to use the Chrome
browser to navigate the web.

What I tried was space+dot2+dot8 to force the next character to be treated
as an ALT character, followed by space+dot3, to force alt+cursor left.
However this is interpreted as just cursor left, so the alt part seems to be
completely ignored.

I think this behavior is seen on other control characters as well (e.g.
shift or control).

With kind regards,

Henk.
