ToDos in Priority order:

Known Bugs:
- some timing issues for some users that leads to an delay to read incomming messages
- for some users fenrir eats the orca key
- in special cases next word skipps a word, "word<12 spaces>word2<12 spaces>word3 (storm_dragon)
- Fenrir key sometimes wents crazy? (maybe this is if fenrir key is released before other keys)
- spellcheck triggers twice if there are two spaces after an word and you arrow over them
- mouse is not usable on desktop with fenrir running (it waits for key events, need to sync here)
Glitches
- For example, in screen, it just tells me bell in window, but doesn't tell me which one. (southernprince)
- alpine seems to have problems (just small glitches) (southernprince)

- move from VCS to VCSA and parese the Attributes
http://linux.die.net/man/4/vcsa
http://man.cx/vcsa(4)/de
http://manpages.org/display-vcsa/7
https://en.wikipedia.org/wiki/Virtual_console
every second byte is a attribute others are text. fast way: c[::2],c[1::2]

- implement speechdriver espeak
https://github.com/relsi/python-espeak

- detect collumns in TTYs automaticaly. 
it seems we have this info in vcsa

- get current cursor
- shortcut handling

0=down, 1=press, 2=hold
2KEY_SHIFT, 1KEY_A = say_current_line_cursor
- implement command structure
- implement speechdriver speechd

- autodetect current TTY maybe with (PAM or a sys folder)
cat /sys/devices/virtual/tty/tty0/active 
http://serverfault.com/questions/306854/how-to-find-out-the-currently-active-linux-virtual-terminal-while-connected-via

http://stackoverflow.com/questions/12384772/how-can-i-capture-mouseevents-and-keyevents-using-python-in-background-on-linux
maybe TTY in RAW MODE

- Settings (make it configureable)
- improve differ speed
- lock mechanism for threads
- restructure loops to listen for events
  inputloop -> does block with an select
  commands -> a new thread should spawned from inputloop
  updatescreen -> maybe we could watch it with inotify vsca should support polling COMMENT: sadly not possible, poll events not fired as expected
  https://github.com/seb-m/pyinotify/wiki/Tutorial
<Example Code>
import pyinotify
import glob
class Identity(pyinotify.ProcessEvent):
    def process_default(self, event):
        p = event.pathname
        print(p)

wm = pyinotify.WatchManager()

notifier = pyinotify.Notifier(wm, default_proc_fun=Identity(), timeout=5)
wm.add_watch('/sys/devices/virtual/tty/tty0/active', pyinotify.IN_CLOSE_WRITE)
for file in list(glob.glob('/dev/vcsa[0-64]')):
    wm.add_watch(file, pyinotify.IN_CLOSE_WRITE)
    print(file)

try:
    while 1:
        notifier.process_events()
        if notifier.check_events( timeout=1000):
            notifier.read_events()
            print('events')
        else:
            print('timeout')
except KeyboardInterrupt:
    notifier.stop()
    print('fin')
