How to use features-export drush command?
I figured out the syntax. 

First, you have to learn the name of the component. Use the features-components command for this. 

Then, when you know the component, do drush features-export my_module_name 'component_type:component_name'. That will create a module with the component you specified in it. 

So in my case, I would do drush features-export my_module_name 'field_base:field_address_1. 

If you want to add multiple components, you have add them to an existing, enabled module. So if I want to add another component to the features module I just created, I would do

$&gt; drush en -y my_module_name
$&gt; drush features-export -y my_module_name 'field_base:field_address_2
