If I want to do piece-wise I can even implement it with a single line in
the header. (I usually don't want that, though).
Your way is tedious unless you are very certain about your structure.
Say I want a point in between:
> 1. <2-> Two more to go
> 2. <3-> One more to go
I would have to renumber stuff throughout the reminder of the slide.
Personally, I find that I often do, but perhaps this is a flaw in my
organization skills?
I would rather use the IMO more stable \pause command, but this is still
not elegant. What I ask for is a more general approach, which is
perhaps not specific to beamer/does not rely on LaTeX commands.
Consider an example with a block
#+begin_src org
** Beamer title :B_frame:
:PROPERTIES:
:BEAMER_env: frame
:END:
- points leading up to example
- I want a pause before presenting the example
## I could put in a pause here,
## but it belongs to the example.
## Logically, it thus does not belong here
*** pause :B_ignoreheading:
:PROPERTIES:
:BEAMER_env: ignoreheading
:END:
\pause
## I have to impose a pause in a separate block.
## But this is an annoying hack.
*** Letting variables take on value. :B_example:
:PROPERTIES:
:BEAMER_env: example
:END:
## a \pause is no good here, as the title is not hidden
Let $x = y$ and $y=1$. Then $x=1$.
#+end_src
It would be nicer to have a pause tag/property, say. It would also be
more org-ish, and could work across exporters. Pause of the <n> syntax
is not that pretty, and is beamer-specific.
Perhaps in general it would be more beneficial to think of a
org-e-slides, and a specialized org-e-slides-beamer? (The main reason
for using Beamer to me is math and note support).
