+
+This operator allows to quickly exchange text inside a buffer.
+
+Eg. To exchange two words, place your cursor on the first word and type `sxiw`.
+Then move to the second word and type `sxiw` again. Note: the {motion} used in
+the first and second use of `sx` don’t have to be the same. Note 2: this is
+dot-repeatable, so you can use `.` instead of `sxiw` for the second word.
