User Guide
From opening your first file to immersive split-screen writing — the everyday flow of Mark::Blocks.
Home & Tiles
Launching the app opens the home screen. Recently opened files are laid out as tiles, true to the Metro Start screen:
- Click a tile to open the file.
- Tile colors follow the accent color.
- The home background is customizable — see Customization.
File Tabs
With multiple files open, Metro-style file tabs appear at the top:
- Click a tab to switch files.
- Tabs animate smoothly between files.
- On Windows Phone, immersive mode hides the tabs and gives all screen space to content.
Writing
The editor is based on RichEditBox:
- Type Markdown source directly.
Ctrl+Fopens find.Ctrl+Z/Ctrl+Yfor undo / redo.
Preview
The preview is rendered live by an IE11 WebView with code highlighting, formulas and diagrams. The preview background can be switched between three styles.
Split View (Windows only)
On Windows / Windows RT you can enable Split View: writing on the left, preview on the right, side by side.
Sync Scroll Rules
Split View’s synchronized scrolling follows a “whoever moves, leads” local rule:
- Scrolling the RichEditBox (writing pane) -> the preview pane follows.
- Scrolling the WebView (preview pane) -> the writing pane does not move.
This makes it easy to compare while writing, without disturbing the caret while reading the preview.
Tip: Windows Phone screens are too small for Split View. The phone uses two independent modes — “clean write” and “clean preview” — switched as needed.
Immersive Mode (Windows Phone only)
With immersive mode enabled on the phone, the file tabs are hidden, maximizing writing / preview space — ideal for long-form writing.
Export HTML
Choose “Export to HTML” in the file menu and the app packages the current document with its styles into a standalone HTML file, ready for offline distribution or direct opening in a browser.
Autosave
Autosave can be toggled in Settings with a selectable frequency. Once enabled there is no need for manual Ctrl + S, protecting you from accidental loss.
