kkmouth will not work for my case

Kmouth is not a screen reader so won't work for my use case.  A little
reading of the man page made it clear this will not read any command
responses and likely won't execute commands entered either other than
itself.  This is good since I avoid testing something that won't work.  I
always like to know I'm arriving at a dead end before arriving.
I don't know how well orca works under kde but for the foreseeable future
sighted installers would have to install the entire mate accessibility
stack into kde to get any of this working.
