In version 2.0.0 I added the local scroll speed to the theme’s primary localized data so you can easily tweak the speed (default is 1000ms).
Total’s wp_localize data
Altering The Local Scroll Speed
Now to alter the speed is very simple, if you noticed the array data above (in the dark screenshot) has the ‘wpex_localize_array’ filter added to it so via a child theme we can easily hook into that filter to alter anything! Below is the code you would add to your child theme’s functions.php file to alter the local scroll speed.
