+# WHAT ONE PRESS OF `n` TAKES, and why that is not one answer. A pane's rows
+# decide it (output_pane.Grain, read in Pardes.lookSpanIn):
+#
+#   free text — a terminal, a file, a PDF — is stepped WORD by word, several
+#   stops to a line, because a line of it may name several places at once (the
+#   `ls` row in ttylook.snap hops big.txt -> plain.txt -> sub);
+#
+#   a RESULTS BUFFER is stepped ROW by row, on the location at the head of the
+#   row, because a row there IS one location and the words after it are the
+#   MATCHED TEXT — the same hit, spelled out. That text is full of look-able
+#   words, and stopping on them was stopping on the same result twice.
+#
+# This script is the second rule. Row 2 below matched on a line that mentions
+# `sub/b.txt`, so the old word-grained walk stopped there before it ever
+# reached row 3; now `n` presses and rows correspond one to one, and the fourth
+# press wraps the ring back to row 1.
+#
+# LARGEST from the head, so a path with a BLANK in it is one span rather than
+# the word in front of it: `two words.txt` selects whole and opens.
