t t _8 n Wn t i t i! n X| p | S( s The primary key event handler for Orca. Keeps track of various
attributes, such as the lastInputEvent. Also calls keyEcho as well
as any local keybindings before passing the event on to the active
presentation manager. This method is called synchronously from the
AT-SPI registry and should be performant. In addition, it
must return True if it has consumed the event (and False if not).
Arguments:

loosely be based on signals, where the exit code will be the
signal used to terminate Orca (if a signal was used). Otherwise,
an exit code of 0 means normal completion and an exit code of 50
means Orca exited because of a hang.i i s ?stnvld:e:u:t helps user-prefs-dir=s enable=s disable=t setups gui-setups
