 ==== Tracking Position with the Zip API
 
-If you need to track the source row and column while reading and updating your zipper, create your zipper with `:track-position true` option.
+If you need to track the source row and column while reading and updating your zipper, create your zipper with `:track-position? true` option.
 Note that the row and column are 1-based.
 
 [TIP]

-If you have no interest in the zipper updating positions when the zipper changes, but are still interested in node positions, you can use a zipper without `:track-positon true` option.

 These options will be carried by the zipper and live for the life of the zipper.
 Current options are:
 
-* `:track-position` - see <<position-tracking>>
+* `:track-position?` - see <<position-tracking>>
 * `:auto-resolve` - see <<custom-auto-resolve>>
 
 After making changes via a zipper, the final step is typically to call `root-string` or `print-root`.

 I personally prefer the map notation, but, as a rule, favor rewrite-clj v0 over rewrite-cljs because rewrite-clj v0 is the more widely used library and thus changes affect more users.
