Click, or hover, on any menu item in the image to read about that command.

Gale 10Aug16: Commenting this out until clarified. Non-default is "on". I cannot obviously see that the setting affects zooming at selections, except for the start of the track. At the start of the track, if left of zero is off, zoom is not centered. This needs explaining better, if left in.
If "Enable scrolling left of zero" is set to be "off" (the non-default setting) then the center of the selection will be positioned at the center of screen.
James 15Apr17: Add some images from elsewhere?

Zoom In

  • View > Zoom > Zoom In: Doubles the current zoom level.

Zoom Normal

  • View > Zoom > Zoom Normal: Reverts back to Audacity's default zoom, where you can see 5 - 10 seconds at a time.

Zoom Out

  • View > Zoom > Zoom Out: Cuts the current zoom level in half.
PRL 28May15: Time at screen center is unmoved, unless too near the start of track and "Enable scrolling left of zero" is off

Zoom to Selection

  • View > Zoom > Zoom to Selection: If you have audio selected, this zooms and scrolls so that the selection just fits in the window.
PRL 28May15: Make a clip, use time shift to drag it partly left of zero, double click the clip, and use this command. Results are anomalous. Width is correct for the selection but horizontal position is not. "Enable scrolling left of zero" does not change that.
