Critical Apparatus and Sigla Management

In the Criterion editor, a Siglum (plural Sigla) represents a reference to a source, such as a manuscript or printed edition. Sigla are used in critical editions to annotate textual witnesses and sources.

1. Go to References > Sigla Setup... or press F6
2. Click Create

Siglum Definition Interface:

Formatting toolbar available above all fields offers:

• Font selection (system fonts)
• Bold, Italic, Underline, Strikethrough
• Superscript/Subscript
• Insert symbol (β)
• Insert existing siglum (Ω)
• Keyboard mapping

You can insert a siglum reference directly into your document using:

• Menu: References > Add Siglum
• Shortcut: F3
• Toolbar: Click the Add Siglum icon
• Context menu: Right-click in Main Text or apparatus boxes

Selection Popup:

• A scrollable list of defined sigla appears
• Click desired siglum to insert at cursor position
• If no sigla defined, system prompts to open Sigla Setup

Once inserted:

• The siglum is visually represented at the insertion point
• Hovering shows a tooltip with first 70 characters of associated Manuscript(s) field
• If text exceeds 70 characters, it is truncated with ellipsis (…)

1. Open References > Sigla Setup...
2. Select siglum from left panel
3. Edit fields in right panel
4. Click Save to apply changes

Duplicate: Click the 📝 icon. Copy appears with incremented suffix. Delete: Click the 🗑️ icon.

	Warning: This operation is irreversible.

For sharing or reusing sigla:

Import:

1. Load a .siglum file via the Import button
2. If naming conflicts detected, choose:
- Replace: Override existing siglum
- Discard: Keep existing, ignore imported
- Keep Both: Import with suffix (e.g., A → A_1)

Export:

1. Save current sigla list as .siglum file via Export button
2. Choose destination path and filename (default: sigla_export.json)

A Critical Note links a selected lemma (word or phrase) in the main text to one or more textual variants or annotations (readings) in the apparatus.

	Note important: Critical apparatus notes can be inserted only in the Critical Text section. They are not available in Table of Contents, Introduction, or Bibliography.

Step 1: Add Lemma

1. Select text in the main text that you want to annotate
2. Add note via:
- Menu: References > Add Note > Apparatus n (Critical)
- Toolbar: Click "Add Note" icon
- Context menu: Right-click in main text
- Keyboard: F5

Lemma Display Logic:

• If selected text > 6 words: shows “first 3 words … last 3 words”
• If ≤ 6 words: shows “first word … last word”

Step 2: Add One or More Readings

Each reading can consist of:

	Note: Manual separators (,, ;) must be added by the user.

Option A: From Main Text

• Modify the lemma directly in the main body
• All linked notes are updated automatically

Option B: From Apparatus Box

• Only Free Text can be edited directly
• Structural elements (lemma, separator, type, siglum) must be deleted manually and reinserted using appropriate menu/toolbar/shortcut

	Warning: Changes to reading types affect only future entries—not past ones.

Option A: From Main Text

• Delete the selected lemma text
• System automatically removes the note and its readings

Option B: From Apparatus

• Use Delete button in the dropdown menu

Each entry shows:

• Line number (auto-calculated)
• Lemma (e.g., vincit])
• Readings (e.g., vicit B, D)
• Reading type, sigla, free text
• Reading separators (:)
• Apparatus entry separator (;) → auto-inserted by system

If a note spans multiple pages, it's printed on the first page only. Multiple notes for the same line are separated using the apparatus entry separator automatically.

Customize default separators and font styles for key structural elements in apparatus notes. Changes apply consistently across editor view, print preview, printed documents, and PDF exports.

For each separator element:

• Set custom separator: Any symbol, letter, or punctuation (max 3 characters)
• Apply font styles: Toggle bold, italic, and/or underline
• Disable separator: Select “None” if no separator desired

	Note: Changes are immediately reflected in text editor, print preview, PDF export, and printed documents.

Define the appearance and naming of each reading type representing textual changes (additions, omissions, deletions, transpositions).

All font styles (bold, italic, underline) are disabled by default but can be enabled.

Change Label:

• Replace default abbreviation with custom label
• Maximum: 10 characters (letters, numbers, punctuation)
• Example: omiss. or +

Set Font Style:

• Toggle Bold, Italic, Underline for each reading type
• Styles applied in all views and exports

	Note: Use “Save and apply to all” to apply changes to all apparatus notes, including existing ones.
