-;; Using the `word at point' as a topic suggestion
-;; ===============================================
+;; Using the word at point as the default topic
+;; ============================================
-;; By default, the `woman' command uses the word nearest to point in
-;; the current buffer as a suggestion for the topic to look up. The
-;; topic must be confirmed or edited in the minibuffer. This
-;; suggestion can be turned off, or `woman' can use the suggested
-;; topic without confirmation* if possible, by setting the user-option
-;; `woman-topic-at-point' to nil or t respectively. (Its default
-;; value is neither nil nor t, meaning ask for confirmation.)
+;; The `woman' command uses the word nearest to point in the current
+;; buffer as the default topic to look up if it matches the name of a
+;; manual page installed on the system. The default topic can also be
+;; used without confirmation by setting the user-option
+;; `woman-use-topic-at-point' to t; thanks to Benjamin Riefenstahl for
+;; suggesting this functionality.
