[O] Drawers and visibility cycling

[Steven Arntson]

I've never been able to get drawers to go through a visibility cycle,
and so have always avoided using them, but now I have a use-case in
which they would be very handy.

Here's my "not working" process:

+ type some sample text.
+ select the region and do `C-c C-x d'
+ I'm queried for the title of the drawer and type "test"

The result looks like this:

:testdrawer:
test content
:END:

However, when I put point on :testdrawer: and hit TAB, it doesn't go
through any kind of cycle---just sits there.

What am I doing wrong?

Thank you,
