Math & equations

Zorite renders LaTeX math and lets you edit it visually — a fraction is a real stacked box you click into, not a string you hand-edit. Both inline and display math work anywhere you write Markdown.

Writing math

Wrap math in dollar signs:

• Inline — $…$ sits in a line of prose, e.g. the area is $\pi r^2$.
• Display — $$…$$ on their own lines render as a centered block.

Both typeset to crisp formulas with KaTeX-grade coverage. A lone $ in prose (like it cost $5) stays literal. You can also insert a block from the / command palette — type / and pick Math.

The structural editor

Click or arrow into a formula to edit it in place with a two-dimensional editor (Casio-Natural-Display / MathQuill style). The caret moves through the structure — into a numerator, under a root, between matrix cells — rather than along a line of LaTeX.

• Type naturally — letters and operators insert as symbols; ^ starts a superscript and _ a subscript, and the caret descends into the new box.
• \command autocomplete — type \ and a name (\alpha, \sqrt, \frac, …) for a scrollable menu of ~100 commands; Enter, Tab, Space, or { inserts the highlighted one — so \hat{ opens the accent’s slot just as it would in LaTeX.
• Accents — \hat, \widehat, \bar, \vec, \tilde, \dot, \ddot, \check, \breve (by command, or the palette’s bottom row) place an editable base under the mark; the caret drops into it. Backspace just after an accent peels the mark off and keeps what was under it.
• Symbol palette — a floating panel of one-click structures and symbols (fractions, roots, matrices, the Greek alphabet, relations, big operators, …).
• Select and wrap — select a sub-expression (Shift-arrows or drag with the mouse; double-click a cell, triple-click a row), then apply a fraction, root, delimiter, or accent — from the palette or by typing its \command — to wrap it instead of inserting an empty one.
• Matrices — insert a grid and add or remove rows and columns as you go.
• Undo / redo — ⌘Z, ⌘⇧Z, ⌘Y (Ctrl on Windows and Linux).

Arrow past a formula’s edge (or press Esc) to flow the caret back into the surrounding text, the way arrowing out of a table cell leaves the table.

Alignment

A display formula is centered by default. Right-click it for Align → Left / Center / Right — the choice is saved per-formula, so it stays put when you edit.

Copy & export

Right-click any rendered formula for:

• Copy LaTeX — the formula’s source, to paste elsewhere.
• Export PNG — a transparent raster at display resolution.
• Export SVG — a self-contained vector with the glyph outlines embedded, so it renders correctly even where the math fonts aren’t installed.

What’s supported

Rendering is essentially complete — anything KaTeX can typeset, Zorite renders: every symbol, accents, blackboard-bold and script fonts, align / cases environments, and more.

The 2-D editor handles the common core — fractions, roots, super/subscripts, matrices, delimiters, accents, and ~100 symbols. A formula that uses something outside that (a font like \mathbb, a multi-line environment) still renders perfectly; you just edit it as raw $…$ LaTeX rather than in the structural editor.
