   A numeric argument restricts replacement to matches that are surrounded

+  What if you want to exchange @samp{x} and @samp{y}: replace every @samp{x} with a @samp{y} and vice versa?  You can do it this way:
+
+@example
+M-x query-replace @key{RET} x @key{RET} @@TEMP@@ @key{RET}
+M-x query-replace @key{RET} y @key{RET} x @key{RET}
+M-x query-replace @key{RET} @@TEMP@@ @key{RET} y @key{RET}
+@end example
+
+@noindent
+This works provided the string @samp{@@TEMP@@} does not appear
+in your text.
