Glyphs
Every mark typo3_icon_lookup can answer with. Type what the thing does, not what it looks like — the index holds the drawings by purpose and by name.
32 of 392 glyphs
The identifier is the answer
A glyph is asked for by name, so the name is on the tile rather than
under a pointer — a tooltip cannot be reached from a keyboard and cannot be
found on the page. That is also what makes the wall searchable by the browser's
own find.
