Org transforms heading levels into Beamer’s sectioning elements, frames and blocks. Any Org tree with a not-too-deep-level nesting should in principle be exportable as a Beamer presentation.
org-beamer-frame-levelor ‘H’ value in a ‘OPTIONS’ line (see Export Settings).
Org overrides headlines to frames conversion for the current tree of
an Org file if it encounters the ‘BEAMER_ENV’ property set to
‘frame’ or ‘fullframe’. Org ignores whatever
org-beamer-frame-level happens to be for that headline level in
the Org tree. In Beamer terminology, a full frame is a frame
without its title.

When ‘ignoreheading’ is set, Org export ignores the entry’s headline but not its content. This is useful for inserting content between frames. It is also useful for properly closing a ‘column’ environment.
When ‘BEAMER_ACT’ is set for a headline, Org export translates that headline as an overlay or action specification. When enclosed in square brackets, Org export makes the overlay specification a default. Use ‘BEAMER_OPT’ to set any options applicable to the current Beamer frame or block. The Beamer export back-end wraps with appropriate angular or square brackets. It also adds the ‘fragile’ option for any code that may require a verbatim block.
To create a column on the Beamer slide, use the ‘BEAMER_COL’ property for its headline in the Org file. Set the value of ‘BEAMER_COL’ to a decimal number representing the fraction of the total text width. Beamer export uses this value to set the column’s width and fills the column with the contents of the Org entry. If the Org entry has no specific environment defined, Beamer export ignores the heading. If the Org entry has a defined environment, Beamer export uses the heading as title. Behind the scenes, Beamer export automatically handles LaTeX column separations for contiguous headlines. To manually adjust them for any unique configurations needs, use the ‘BEAMER_ENV’ property.
If ‘BEAMER_ENV’ is set, Org export adds ‘B_environment’ tag to make it visible. The tag serves as a visual aid and has no semantic relevance.
