Just above the layer table, at the far left of the top button menu, is a text entry area, with a button containing a blue triangle icon to the left. The name of the current layer is displayed in this area. This can be used to find layers by name. One can enter the first few characters of a layer name into the text area, then press the button to the left. The button icon will change to two triangles, and the layer table will scroll to the first matching layer found (if any), as the current layer. Clicking the button a second and subsequent time will scroll to the next and later matches. Though the text in the entry area will take on the selected layer name, the search string is retained internally as long as the two-triangle icon is displayed on the button. This will revert to the single triangle after a few seconds if not clicked. When using the layer:purpose form, both the layer and purpose strings are handled independently, and both can contain just the first few characters of the actual layer and purpose names.
