spasarok on "List of Default Customizer Controls"

I'm working on a variant of the Twenty Eleven theme and am currently tweaking the Customizer. I'd like to move the Header Text Color control from the Colors section to the Site Title & Tagline section.

I know that I can do this with the Link Colors control using the code:

$wp_customize->get_control( 'link_color'  )->section   = 'title_tagline';

Here link_color indicates the control. What do I have to use to indicate the Header Text Color control? Is there a reference list of all the default controls?
