I am new to WordPress, and have been learning to add options to the Theme Customization page). I read the WordPress Documentation on Theme Customization API, and was able to locate, in other themes, where they had the PHP that added these options and made these changes. From there, I could add more options and change the available ones.
However, I can't locate in Coraline where they add these options. The other themes I have played with have had them in "functions.php", but in Coraline I can not locate them there. I have basically just been using "ctrl-f" to locate where someone calls "customize_register". This led me to the right place for other themes, however I can't locate this called in the files for Coraline. Am I just looking for the wrong things, or in the wrong places?
Any direction would be appreciated, thank you.
