The Text Editor pane recognizes any text between the characters |> and <| as a text field. You can search forward through the text from the insert point to find and select each field using the Replace |>field<| item of the Find menu. The Replace |>field<| submenu provides three options: Expand, Next, and Previous:
When the caret in the Text Editor pane is between field delimiters, choose Expand to search in both directions and select the entire field and its delimiters.
Use Next to search forward from the insert point and select the next field.
Use Previous to search backward from the insert point and select the previous field.
