{{ednote|'''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.    
{{note|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. }}}}

<div id="zoomin"></div>
== [[Zooming|Zoom In]] &nbsp;<font size="-1">{{shortcut|CTRL + 1}}</font> ==
* <span class="menu">View > Zoom > Zoom In</span>: Doubles the current zoom level.
Zooms in on the horizontal axis of the audio, displaying more detail over a shorter length of time.  You can also use the [[Tools Toolbar#zoom|zoom tool]] to zoom in on a particular part of the window.

<div id="zoomnormal"></div>
== [[Zooming|Zoom Normal]] &nbsp;<font size="-1">{{shortcut|CTRL + 2}}</font> ==
* <span class="menu">View > Zoom > Zoom Normal</span>: Reverts back to Audacity's default zoom, where you can see 5 - 10 seconds at a time.
Zooms to the default view, which displays about one inch per second.

<div id="zoomout"></div>
== [[Zooming|Zoom Out]] &nbsp;<font size="-1">{{shortcut|CTRL + 3}}</font> ==
* <span class="menu">View > Zoom > Zoom Out</span>: Cuts the current zoom level in half.
Zooms out, displaying less detail over a greater length of time.
{{ednote|'''PRL 28May15''': Time at screen center is unmoved, unless too near the start of track and "Enable scrolling left of zero" is off}}

<div id="zoomtoselection"></div>
== [[Zooming|Zoom to Selection]] &nbsp;<font size="-1">{{shortcut|CTRL + E}} </font> ==
* <span class="menu">View > Zoom > Zoom to Selection</span>: If you have audio selected, this zooms and scrolls so that the selection just fits in the window.
Zooms in or out so that the selected audio fills the width of the project window. Its most useful purpose is to zoom in when the selection is only a small part of the visible waveform. 
{{ednote|'''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.}}
