Change Waveform Volume in 11.2

I’m using WaveLab 11.2, I started on 9x and I seem to rememberer being able to select a waveform left, right or both and being able to manipulate the volume by dragging the mouse up or down with possibly a combo key (command, option etc…) as desired, I do not see a way to do that same operation in 11.2 can anyone say if I am imaging things or is it no longer possible with 11.2’

Thanks in advance

Using the audio editor or a clip in the montage?

I’m using the audio editor.

Thank you so very much for pointing me in the right direction, I appreciate it.
