Left, no the other Left.

Is there any way to edit just one channel of a stereo waveform? The very short noise at a particular spot… is at exactly the same time as an important sound. Can i alter the noise on the one channel without affecting the other channel. I realize that if I DELETE something that it will throw timing off, but what about a simple reduction in volume?

split stereo track”, then edit the one track, then join them back together with “make stereo track”.

There is a plug-in which can be used to repair defects on one channel by patching-in a piece of the other … https ://wiki.audacityteam.org/wiki/Nyquist_Effect_Plug-ins#Repair_Channel

Exactly what I want. Thanks so much, Trebor.
