Unmarked 1.1 turns your document into slides

Unmarked 1.1 adds Present. Press ⌥⌘P or click the play button and the open document becomes full-screen slides.

H1 and H2 headings start a slide. Horizontal rules do too. The same document stays underneath, so there is no deck file to build or rebuild when the writing changes.

Arrow keys, Space, Page Up, and Page Down move through the presentation. B blanks the screen to black, W to white, and Esc returns to the section you were presenting.

The Present guide has the full slide-break rules and controls.
