How do I mark points in the waveform?

I get the idea. Thanks. I have been using the Fade In and Fade Out effects for cross fades, but Envelope seems more precise.

You might want try a neat new crossfade plugin that Steve developed recently - see this thread: Cross Fade Classic

I have been testing it for him and I find it works a treat.

And in terms of fade-outs Steve’s new ProFade give a much better sounding fade out than Audacity’s standar liner fade - see: Professional sounding fade out.
I use this one all the time now.
