Hi Amanda,
You cannot really "generate" wave signals via NVDA. However, you
can play a wave file using NV wave module, with the name of the
file to play as a parameter (Mick knows more about this than I
do; I rarely use NV wave player). And you cannot generate
multiple tones using tones module.
Cheers,
Joseph

So I have another question...
Tones.beep doesn't output multiple frequencies at once. To do
this I
assume I will need to generate wave data (usually done as floats
between
-1.0 and 1.0) and feed them to nvwave.wavePlayer. The problem
is,
wavePlayer.feed takes an str argument, and I can find very little
information about the format of this string. So, how do you
generate
waves and play them?

Hi Amanda,
1. You can get the name/identifier for the gesture by doing
gesture.displayName. The complete list of valid gestures is
located in NVDA
core under source/vkCodes.py.
2. To send the gesture to the operating system, at the
beginning of the
script routine, write gesture.send().
3. I usually use print statements in the script body to locate
errors. When
this is done, NVDA will output stdout as part of the log viewer
text (log
file). Of course in production releases, remove traces of
debugging once you
know your script is working as advertised.
Any other questions?
Cheers,

Hi, these are just a few dumb questions while I experiment with
a few
plugins before actually getting started on my project.
First, is there a comprehensive list of gestures and their
names?
Second, normally a script won't execute and then send the
gesture to the
operating system, but is there a way to make it do this?
Finally, and this is more of a debugging question, what's the
easiest way to
get error messages? I've been copying my code to the global
plugins folder
and then reloading the plugins, but this doesn't generate any
messages when
things don't work.
