Here are some more zooming tips…
- You can use the keyboard shortcuts Command+square brackets ([ ]) (Mac) or Control+square brackets ([ ]) (Windows) to zoom in and out horizontally or if you have the Keyboard Focus enabled on the Edit Window using the R & T keys will zoom out and in horizontally.
- To return to the previous zoom setting, which is especially useful when you have zoomed right in to look at the actual waveform, Alt+Click on either of the horizontal zoom buttons or use the keyboard shortcut Command+Alt+E (Mac) or Control+Alt+E (Windows).

- There are two modes to the Zoom Tool, Normal and Single. Normal is the original Zoom Tool and when Single is selected the previously selected Edit tool is automatically reselected after zooming. This works really well in conjunction with the return to previous zoom setting above.
- To zoom out all audio tracks and reset waveform display to the default settings, either double click the Zoomer tool or use the keyboard shortcut Alt+A.
- To set all audio track waveform heights to match the waveform height of the topmost audio track in the Edit window, hold down Control+Shift (Windows) or Command+Shift (Mac) and click on any of the Zoom buttons. Note that when you do this any waveform height offsets will be lost.
