Indirect allows you to return a list of elements from selectors found within a set of elements from a selector. It's pointers for jQuery, which can be very useful when dealing with filtering and categorizing event actions like showing/hiding relating navigation elements for mobile.

/**
 * Indirect returns elements found by the called selector within the
 * provided attribute.
 *
 * > <a href="#" class="show-menu" data-show-navigation=".main-navigation">
 * > $('.show-menu').indirect('[data-show-navigation]')
 *
 * This will return the equivalent of calling $('.main-navigation') which
 * allows you to indirectly find a list of elements from a set of
 * existing "pointer" elements.
 *
 * @param  {string} attr String name of attribute containing selector
 * @return {[]}          jQuery list of selector elements
