> ScreenFlow enables you to color code clips in the timeline for quick navigation and labelling. You can create labels from the Edit menu or by right-clicking the clip. One or more clips need to be selected in the timeline for the Label menu item to be enabled.
> When the Label menu item displays, click the desired color to identify the selected clips. Click X to remove the color label from the clip(s). There are four colors available for labeling.
