Shouldn't `("@" "\\alert{%s}" nil)' be added by default?

Hmm, I am not sure, because \alert is of course not defined in normal LaTeX export. And maybe it would even be better to redifine bold emphasis as alert
for beamer export?

For me, bold and alert are 2 different beasts. Some beamer styles even display them differently (different colors, for example). Better would be not to mix
them, IMHO.

- How to get "frame breaks", without modifying the resulting TeX file (by adding a frame option `allowframebreaks' -- similar to the `fragile'

Just put [allowframebreaks] into the :BEAMER_envargs: property of
the node that becomes the frame.

That does work. Thanks.

However, couldn't we have that on by default on all nodes? For sure, some people won't remark some text is cut off in the output beamer presentation,
when the option is not set.

I believe turning this on for all frames has drawbacks, like
loosing overlay capability?

I'm not sure I understand the point but...

However, I guess it does make sense to have a global variable to
set default options for frames, I guess.  I'll put that on my list.

OK. Thanks.

By the way, how are we supposed to add that property in the most easiest manner? I never really used column view, but I have troubles when using it

On the node where I want to add that property, I do:
- `C-c C-x C-c' to enter column view
- `right' (arrow) to go in the second column
- `e' to edit the property
... but I'm put in a tag selection menu... What am I doing wrong?

That happens at the BEAMER_env property and give you a way to select the environment with a single key, for example `e b' for block. If you move the cursor to the field for env args, e will give you a prompt where you can

Whether in org-mode or in org-beamer-mode, when typing `e' on the second column, it opens the tag selection interface in the minibuffer. But, here,
what I'm trying to add is a property, not a tag...?

Indeed you are changing the tag, but the property will change along
with it (check it!).  The idea is that the property is *tracked* by
a tag, to make the current value constantly visible.  I use the tag
interface just because it exists and is simple to use.

Pressing TAB allows me free edition, but what's inserted at the node is a

Which will cause a change in the property as well, I believe.  I know
it is confusing - but once you've got your head around this, it will be
very useful.

PS- An idea: wouldn't it be good (*iff* easily feasible) to load
org-beamer-mode when opening an Org file whose LaTeX class is beamer?

That could be done, but you can also set the startup option.
But yes, it is one more think to remember...
