Question: How does one use Beamer's \only command with blocks? (Successfully,
with org-mode's beamer export, I mean.)
I found in the manual that you can give an overlay specification using the BEAMER_ACT property... ok... but that's
not the same as \only because, when a latex chunk is marked \only<1>, it takes *no space* on <2->.
Using <1> and <2> causes the <2> to appear lower than the <1>. That's not what I want.
Hacking it with #+latex: lines is even worse, as explained in the example below.
I suppose there must be a way to do it, albeit undocumented. Or maybe it's
simply not supported, in which case I would have to write the LaTeX directly.
Annoying, but I'll do that if there's no alternative.

** Frame (beamer_act, not quite right)
*** The problem on this frame
I want Block 1 and Block 2 to occupy the same space on successive slides.
*** Block 1 :B_block:
:PROPERTIES:
:BEAMER_env: block
:BEAMER_ACT: <1>
:END:
*** Block 2 :B_block:
:PROPERTIES:
:BEAMER_env: block
:BEAMER_ACT: <2>
:END:
** Frame (using #+latex and \only)
*** This is a complete bloody hash.
There is no way to make \verb|\only<2>| come after \verb|\end{block}|.
#+latex: \only<1> {
*** Block 1
#+latex: } \only<2> {
*** Block 2
#+latex: }
