W10, 2.3.2 When editing low amplitude signals it is often necessary to zoom in on the waveform. Zoom to 2x is sometime inadequate. Add a zoom scale factor parameter to the dropdown for Name, etc. that lets you vary the zoom from x to kX rather than 2x. Thanks Jim
If you enable “Advanced Vertical Zooming” (https://manual.audacityteam.org/man/view_menu_zoom.html) you can zoom in very much more.
