Editing and formatting

Switch to the editor

Press ⌘E or click Edit in the top bar to move from preview into the source editor. The same key takes you back. The editor is built on CodeMirror, with Markdown syntax highlighting and its own search (press ⌘F while editing).

Split view

Press ⌘⇧E, or click Split in the top bar, for the editor and the live preview side by side. As you type on the left, the preview on the right keeps up, and the two panes scroll together so the preview follows wherever you are in the source. The formatting toolbar and shortcuts work here too.

Attaching images

Paste an image from the clipboard, or drag an image file onto the editor, and Markappoly saves it into an assets/ folder next to your document and inserts the Markdown reference for you. The image then shows in the preview. The document needs to be saved first, so Markappoly knows where the assets/ folder belongs.

The formatting toolbar

A toolbar appears above the editor in edit mode. Each button applies Markdown to your current selection so you don't have to remember the syntax:

  • Bold, italic, and strikethrough wrap the selected text.
  • H1, H2, and H3 turn the current lines into headings.
  • The list buttons add bulleted, numbered, or task-list markers to each selected line.
  • Quote turns the selected lines into a blockquote.
  • The code buttons wrap a selection as inline code or drop in a fenced code block.
  • Link wraps the selection as a Markdown link and puts the cursor where the URL goes.

Three of these also have shortcuts: ⌘B for bold, ⌘I for italic, and ⌘K for a link.

Save

Press ⌘S to save. If the document has never been saved, Markappoly asks where to put it and defaults to a .md extension. A dot next to the file name in the tab and the status bar means you have unsaved changes.

Start a new document

Press ⌘T for a fresh, blank document. It opens in edit mode in its own tab, ready to type into.
