Abbreviations

Not implemented

Abbreviations are not part of Tachyonn today. An earlier draft of this page
described a .[HTML, HyperText Markup Language] operator; it was never built,
and writing it in a .tac file produces nothing useful.

What to do instead

On a slide, an expansion is usually better spelled out than hidden behind a
hover — the audience is three metres away and can't hover anyway. Two options
that work today:

Expand it the first time, in the text.

The **HyperText Markup Language** (HTML) predates the web's first browser.

Or give the deck a glossary slide and link to it:

## Abbreviations                                 ::abbrev

| Short | Full |
| --- | --- |
| HTML | HyperText Markup Language |
| KaTeX | the math renderer Tachyonn bundles |

…as defined in :[abbrev, the abbreviations slide].

If the same table appears in every lecture of a course, make it a
macro in a tac.config and
insert it with a single >>[<abbrev>].

The What is Tachyonn? page keeps an up-to-date
list of which features are ready and which are still on the way.
