Chips Classes And Listening to Code Blocks

[RicksPlace]

Hi: Has anyone tried just putting their microphone close to their speakers and 
then cursoring up and down through code to see if that would work to read text 
into the TT server?I am wondering if that would cause feedback like my attempt 
to use Stereo Mix.
I am thinking about the ability for the group to hear code blocks for any 
member asking questions about their own scripts. Originally I thought of using 
StereoMix but that caused massive feedback.
