 	Program to use for the |K| command.  Environment variables are
 	expanded |:set_env|.  ":help" may be used to access the Vim internal
 	help.  (Note that previously setting the global option to the empty
 	value did this, which is now deprecated.)
-	When "man" is used, Vim will automatically translate a count for the
-	"K" command to a section number.  Also for "man -s", in which case the
-	"-s" is removed when there is no count.
+	When the first character is ":", the command is invoked as a Vim
+	Ex command prefixed with [count].
+	When "man", "man -s" or an Ex command is used, Vim will automatically
+	translate a count for the "K" command and pass it as the first
+	argument.  For "man -s" the "-s" is removed when there is no count.
 	See |option-backslash| about including spaces and backslashes.
 	Example: >
 		:set keywordprg=man\ -s
