Hallo,=20

I am using the org beamer functionality to produce presentations and I =
am quite happy with it. Saves a lot of time. Thanks for the great work!

There is one thing however I am not sure how to go about. I have found a =
number of answers in the mailing list but none that works for me.=20

The question is about (top) aligning columns in beamer export mode.=20

The following indeed produces two top aligned columns C1 and C2.=20

* Frame
	:PROPERTIES:
	:BEAMER_env: frame
	:END:
	* Columns
		:PROPERTIES:
		:BEAMER_env: columns
		:BEAMER_opt: t
		:END:
		* C1
		:PROPERTIES:
		:BEAMER_col: 0.45
		:BEAMER_env: block
		:END:
		* C2
		:PROPERTIES:
		:BEAMER_col: 0.45
		:BEAMER_env: block
		:END:

My questions:

1. Given that the columns environment is implied by the BEAMER_col =
property, is there anyway to avoid the Columns heading by passing the t =
option implicitly to the columns environment?
	Deleting the Columns entry and setting :BEAMER_envargs: C[t] or =
c[t] or C[T] or c[T] in the Frame or the C1/C2 headings is not producing =
top aligned columns for me.

2. What is the status of BEAMER_opt and BEAMER_envargs properties?
	Are they both still supported and what exactly is the =
difference?

Some more general questions:=20

3. Why is the heading of a BEAMER_col entry ignored by default? Why does =
one have to specify a block environment in order for the heading to be =
visible?=20

4. In some cases the BEAMER_col property results in subsections instead =
of columns in the tex file, why is this? =20


many thanks,=20
