Sean is correct. Leverage the aria-expanded property on a link or button and toggle it between "true" and "false" depending on the state. You can also use aria-controls="idref-of-drawer" to create a programmatic relationship between the title and the drawer.

Although, the more I think about it, for SC 2.4.4 Link Purpose (In Context) you can use the link text by itself. In the "Code_Mocks" example below, they toggle the link text from "Show Code" to "Hide Code". Maintain focus on the link and ensure the code snippet is the next item within the DOM.

I assume when you refer to code folding is that you are collapsing the actual code and showing the function only. If I am right, I would look at the aria role for expand/collapse as this might be all you need.

Subject: Using WAI-ARIA for code folding?

I have been experimenting with ways to present computer source code, using HTML markup.  One of the things I'd like to support is code folding (selectively hiding and showing sets of lines, based on the hierarchical structure of the code):

  http://wiki.cfcl.com/Projects/AxAp/Code_Mocks

It seems like WAI-ARIA attributes could be used for this, as in:

 Example 41 - Treeview
 http://oaa-accessibility.org/example/41/

However, it isn't a very close match to my use case.  Given that someone else may have done work in this area, I thought I should ask for help.  Any suggestions before I start hacking?
