This file is intended to give you an overview of the default keys used
by speakup for it's review functions. You may change them to be
anything you want but that will take some familiarity with key
mapping.
We have remapped the insert or zero key on the keypad to act as a
shift key. Well, actually as an altgr key. So in the following list
InsKeyPad-period means hold down the insert key like a shift key and
hit the keypad period.
KeyPad-8 Say current Line
InsKeyPad-8 say from top of screen to reading cursor.
KeyPad-7 Say Previous Line (UP one line)
KeyPad-9 Say Next Line (down one line)
KeyPad-5 Say Current Word
InsKeyPad-5 Spell Current Word
KeyPad-4 Say Previous Word (left one word)
InsKeyPad-4 say from left edge of line to reading cursor.
KeyPad-6 Say Next Word (right one word)
InsKeyPad-6 Say from reading cursor to right edge of line.
KeyPad-2 Say Current Letter
InsKeyPad-2 say current letter phonetically
KeyPad-1 Say Previous Character (left one letter)
KeyPad-3 Say Next Character (right one letter)
KeyPad-plus Say Entire Screen
InsKeyPad-plus Say from reading cursor line to bottom of screen.
KeyPad-Minus Park reading cursor (toggle)
InsKeyPad-minus Say character hex and decimal value.
KeyPad-period Say Position (current line, position and console)
InsKeyPad-period say colour attributes of current position.
InsKeyPad-9 Move reading cursor to top of screen (insert pgup)
InsKeyPad-3 Move reading cursor to bottom of screen (insert pgdn)
InsKeyPad-7 Move reading cursor to left edge of screen (insert home)
InsKeyPad-1 Move reading cursor to right edge of screen (insert end)
ControlKeyPad-1 Move reading cursor to last character on current line.
KeyPad-Enter Shut Up (until another key is hit) and sync reading cursor
InsKeyPad-Enter Shut Up (until toggled back on).
InsKeyPad-star n<x|y> go to line (y) or column (x). Where 'n' is any
allowed value for the row or column for your current screen.
KeyPad-/ Mark and Cut screen region.
InsKeyPad-/ Paste screen region into any console.
Hitting any key while speakup is outputting speech will quiet the
synth until it has caught up with what is being printed on the
console.

This is the Speakup screen reader. Think of it as a
video console for blind people. If built in to the
kernel, it can speak everything on the text console from
boot up to shutdown. For more information on Speakup,
point your browser at http://www.linux-speakup.org/.
There is also a mailing list at the above url that you
can subscribe to.
Supported synthesizers are accent sa, accent pc,
appollo II., Auddapter, Braille 'n Speak, Dectalk
external (old), Dectalk PC (full length isa board),
Dectalk express, Doubletalk, Doubletalk LT or
Litetalk, Keynote Gold internal PC, software
synthesizers, Speakout, transport, and a dummy module
that can be used with a plain text terminal.
Speakup can either be built in or compiled as a module
by answering y or m. If you answer y here, then you
must answer either y or m to at least one of the
synthesizer drivers below. If you answer m here, then
the synthesizer drivers below can only be built as
modules.
These drivers are not standalone drivers, but must be
used in conjunction with Speakup. Think of them as
video cards for blind people.
The Dectalk pc driver can only be built as a module, and
requires software to be pre-loaded on to the card before
the module can be loaded. See the decpc choice below
for more details.
If you are not a blind person, or don't have access to
one of the listed synthesizers, you should say n.

Speakup is a kernel based screen review package for the linux operating
system. It allows blind users to interact with applications on the
linux console by means of synthetic speech.
Currently, speakup has several issues we know of.
The first issue has to do with the way speakup communicates with serial
ports. Currently, we communicate directly with the hardware
ports. This however conflicts with the standard serial port drivers,
which poses various problems. This is also not working for modern hardware
such as PCI-based serial ports. Also, there is not a way we can
communicate with USB devices. The current serial port handling code is
in serialio.c in this directory.
Some places are currently using in_atomic() because speakup functions
are called in various contexts, and a couple of things can't happen
in these cases. Pushing work to some worker thread would probably help,
as was already done for the serial port driving part.
There is a duplication of the selection functions in selections.c. These
functions should get exported from drivers/char/selection.c (clear_selection
notably) and used from there instead.
The kobjects may have to move to a more proper place in /sys. The
discussion on lkml resulted to putting speech synthesizers in the
"speech" class, and the speakup screen reader itself into
/sys/class/vtconsole/vtcon0/speakup, the nasty path being handled by
userland tools.
Another issue seems to only happen on SMP systems. It seems
that text in the output buffer gets garbled because a lock is not set.
This bug happens regularly, but no one has been able to find a situation
which produces it consistently.
Patches, suggestions, corrections, etc, are definitely welcome.
