Adjust how equations are counted, tagged, and linked inside Obsidian. For details on how math indexing operates, see the [Equation Numbering Guide](../features/equations.md).
| Setting Name | Type & Default | Description |
| :--- | :--- | :--- |
| **Number only referenced equations** | Toggle (`On`) | Only add number tags to equations that have at least one active reference in the note. Unreferenced equations remain unnumbered. |
| **Equation number prefix** | Text (empty) | Appends custom characters before the equation number. Example: `§` renders as `(§1)`. |
| **Equation number suffix** | Text (empty) | Appends custom characters after the equation number. Example: `.` renders as `(1.)`. |
| **Equation number initial count** | Number (`1`) | The starting integer for equation counting. Set to `0` to begin from zero. |
| **Equation number style** | Dropdown (`arabic`) | The numeric formatting system used. Options: `arabic` (1, 2, 3), `alph` (a, b, c), `Alph` (A, B, C), `roman` (i, ii, iii), `Roman` (I, II, III). |
| **Reference link prefix** | Text (empty) | Character string injected before references. Example: `Eq.` renders as `Eq.(1)`. |
| **Reference link suffix** | Text (empty) | Character string injected after references. |
| **Show note title in equation link** | Toggle (`On`) | Format for display links. `On` resolves to `Note Title > (1)`; `Off` resolves to `(1)`. |
Customize the autocompletion popup and fuzzy search indexing behaviors. For search behavior explanations, consult the [Search and Autocomplete Guide](../features/search.md).
| **Modifier to jump** | Key Selection (`Mod`) (1) | Keyboard modifier key held down when selecting a suggestion to jump to the equation instead of inserting it. |
| **Show modifier instruction** | Toggle (`On`) | Shows hint key instructions inside the autocomplete popup window. |
| **Manage Snippets** | Modal Dialog | Add, edit, or remove custom LaTeX command snippets triggered via the Command Palette. |
| **Debug mode** | Toggle (`Off`) | Enables the **Debug** button in the PDF export dialog to open Electron DevTools for inspecting the render webview. |
