This class is experimental, and changes may occur to
interfaces. Development is focussed on tagging/functionality as
the primary driver; as such, support for design aspects is
likely to be lower priority. It requires LaTeX 2025-11-01 or
later. The ltx-talk class is focused on producing (on-screen)
presentations, along with support material such as handouts and
speaker notes. Content is created in a frame environment, each
of which can be divided up into a number of slides (actual
output pages). A simple 'overlay' notation is used to specify
which material appears on each slide within a frame. The class
supports a range of environments to enable complex slide
relationships to be constructed. The appearance of slides is
controlled by a template system. Many of the elements of slides
can be adjusted by setting simple key-based values in the
preamble. More complex changes can be implemented by altering
specific, targeted definitions without needing to rewrite
entire blocks of code. This allows a variety of visual
appearances to be selected for the same content source. The
ltx-talk class has syntax similar to the popular beamer class,
although there are some (deliberate) differences. However,
ltx-talk has been implemented to support creation of tagged
(accessible) PDF output as a core aim. As such, it is suited to
creating output for reuse in other formats, e.g. HTML
conversions, without additional steps.
