Features

VMark is a feature-rich Markdown editor designed for modern writing workflows. Here's what's included.

Editor Modes

Rich Text Mode (WYSIWYG)

The default editing mode provides a true "what you see is what you get" experience:

• Live formatting preview as you type
• Inline syntax reveal on cursor hover
• Intuitive toolbar and context menus
• Seamless markdown syntax input

Source Mode

Switch to raw Markdown editing with full syntax highlighting:

• CodeMirror 6 powered editor
• Full syntax highlighting
• Familiar text editor experience
• Perfect for advanced users

Toggle between modes with F6.

Source Peek

Edit the raw Markdown of a single block without leaving WYSIWYG mode. Press F5 to open Source Peek for the block at cursor.

Layout:

• Header bar with block type label and action buttons
• CodeMirror editor showing the block's Markdown source
• Original block shown as dimmed preview (when live preview is ON)

Controls:

Action	Shortcut
Save changes	Cmd/Ctrl + Enter
Cancel (revert)	Escape
Toggle live preview	Click eye icon

Live Preview:

• OFF (default): Edit freely, changes applied only on save
• ON: Changes applied immediately as you type, preview shown below

Excluded blocks: Some blocks have their own editing mechanisms and skip Source Peek:

• Code blocks (including Mermaid, LaTeX) — use double-click to edit
• Block images — use image popup
• Frontmatter, HTML blocks, horizontal rules

Source Peek is useful for precise Markdown editing (fixing table syntax, adjusting list indentation) while staying in the visual editor.

Multi-Cursor Editing

Edit multiple locations simultaneously — VMark supports full multi-cursor in both WYSIWYG and Source modes.

Action	Shortcut
Add cursor at next match	Mod + D
Skip match, jump to next	Mod + Shift + D
Select all occurrences	Mod + Shift + L
Add cursor above/below	Mod + Alt + Up/Down
Add cursor at click	Alt + Click
Undo last cursor	Alt + Mod + Z
Collapse to single cursor	Escape

All standard editing (typing, deletion, clipboard, navigation) works at every cursor independently. Block-scoped by default to prevent unintended edits across sections.

Auto-Pair & Tab Escape

When you type an opening bracket, quote, or backtick, VMark auto-inserts the closing pair. Press Tab to jump past the closing character instead of reaching for the arrow key.

• Brackets: () [] {}
• Quotes: "" '' ` `
• CJK: 「」 『』 （） 【】 《》 〈〉
• Curly quotes: "" ''
• Formatting marks in WYSIWYG: bold, italic, code, strike, links

Backspace deletes both characters when the pair is empty. Auto-pair and Tab bracket jump are both disabled inside code blocks and inline code — brackets in code stay literal. Configurable in Settings → Editor.

Search & Replace

Open the find bar with Mod + F. It appears inline at the top of the editor area and works in both WYSIWYG and Source modes.

Navigation:

Action	Shortcut
Find next match	Enter or Mod + G
Find previous match	Shift + Enter or Mod + Shift + G
Use selection for find	Mod + E
Close find bar	Escape

Search options — toggle via buttons in the find bar:

• Case sensitive — match exact letter casing
• Whole word — only match complete words, not substrings
• Regular expression — use regex patterns (enable in Settings first)

Replace:

Click the expand chevron on the find bar to reveal the replace row. Type replacement text, then use Replace (single match) or Replace All (every match at once). The match counter displays the current position and total (e.g., "3 of 12") so you always know where you are.

Export Options

VMark offers flexible export options for sharing your documents.

HTML Export

Export to standalone HTML with two packaging modes:

• Folder mode (default): Creates Document/index.html with assets in a subfolder
• Single file mode: Creates a self-contained .html file with embedded images

Exported HTML includes the VMark Reader — interactive controls for settings, table of contents, image lightbox, and more.

PDF Export

Print to PDF with native system dialog (Cmd/Ctrl + P).

Copy as HTML

Copy formatted content for pasting into other apps (Cmd/Ctrl + Shift + C).

Copy Format

By default, copying from WYSIWYG puts plain text (without formatting) in the clipboard. Enable Markdown copy format in Settings > Markdown > Paste & Input to put Markdown syntax in text/plain instead — headings keep their #, links keep their URLs, etc. Useful when pasting into terminals, code editors, or chat apps.

CJK Formatting

Built-in Chinese/Japanese/Korean text formatting:

• CJK-English spacing
• Fullwidth character conversion
• Punctuation normalization
• Smart quote pairing with apostrophe/prime detection
• Technical construct protection (URLs, versions, times, decimals)
• Contextual quote conversion (curly for CJK, straight for Latin)
• Toggle quote style at cursor (Shift + Mod + ')

Document History

• Auto-save with configurable interval
• View and restore previous versions
• JSONL storage format
• Per-document history

View & Focus

Focus Mode (F8)

Focus Mode dims all blocks except the one you are currently editing, reducing visual noise so you can concentrate on a single paragraph. The active block is highlighted at full opacity while surrounding content fades to a muted color. Toggle it with F8 — it works in both WYSIWYG and Source modes and persists until you toggle it off.

Typewriter Mode (F9)

Typewriter Mode keeps the active line vertically centered in the viewport, so your eyes stay in a fixed position while the document scrolls beneath you — just like typing on a physical typewriter. Toggle it with F9. It works in both editing modes and uses smooth scrolling with a small threshold to avoid jittery adjustments on minor cursor moves.

Combining Focus + Typewriter

Focus Mode and Typewriter Mode can be enabled simultaneously. Together they provide a fully distraction-free writing environment: surrounding blocks are dimmed and the current line stays centered on screen.

Word Wrap (Alt + Z)

Toggle soft line wrapping with Alt + Z. When enabled, long lines wrap at the editor width instead of scrolling horizontally. The setting persists across sessions.

Text Utilities

VMark includes utilities for text cleanup and formatting, available in the Format menu:

Text Cleanup (Format → Text Cleanup)

• Remove Trailing Spaces: Strip whitespace from line endings
• Collapse Blank Lines: Reduce multiple blank lines to single

CJK Formatting (Format → CJK)
