Find
Click the Find button on the Display Pane toolbar, to find a layer by name by matching or partially matching it to a search string.
The first occurrence of a matching layer name is highlighted in the pane:
Repeated searches using the Find tool (in effect Find Next) in the Display pane will search from the selected (current) layer downwards. When an item is found it becomes the current layer. If the search from the current layer finds nothing, the search will resume downwards again from the top-most layer.
