Display vertical and timeline rulers

In the Editor panel, the vertical ruler indicates amplitude in the waveform display and frequency in the spectral display. Timeline rulers indicate time location.

To display the vertical ruler on the right side of the Editor panel, select View > Vertical Ruler.
To add a second timeline ruler at the bottom of the Editor panel, choose View > Bottom Timeline Ruler.
If you show timeline rulers at top and bottom, each can display a different unit of time. (See Change units in the timeline ruler or time display.)
