Folding and Longform

Two ways to change how much of your writing you see at once: fold a section away under its heading, or open a whole folder of pages as one longform document.

Folding

Any section can collapse under its heading. Hover over a heading and a small chevron appears in the left margin — click it and everything under that heading (down to the next heading of the same or higher level) tucks away behind a ⋯ hint. Click again to bring it back.

• From the keyboard: ⌥⌘. folds or unfolds the section the caret is in. View ▸ Fold All Sections and Unfold All Sections work the whole page at once — fold everything for a tidy outline of headings, then open just the part you're working on.
• Folds are view state, never content. A folded section is still on the page, still searched, still exported, still shared — folding never touches what's saved. Your folds are remembered per page, so a long reference page stays collapsed the way you left it.
• Editing near a fold is safe: if a heading is deleted, its hidden section simply reappears.

Longform — many pages, one document

Sometimes the pieces want to read as a whole: chapters of a draft, a series of meeting notes, a travel journal. Run Open Folder as Longform… from the command palette (⇧⌘P) and pick any folder with two or more pages — they stack into a single scrolling document, each page a sheet divided by a slim rule that carries its name.

Or hand-pick the pages — they don't need to share a folder. In the Pages palette, tap Select, tick the pages you want (anywhere in the wiki, in any order), then click ⧉ Longform in the bar that appears: they compose into one document in the order you picked them. Chapters 1, 4, and 7; the three meeting notes about one vendor; today's note plus the two pages it references — whatever belongs together right now, reads together right now.

• Everything stays editable. Click into any sheet and write — every change saves back to that sheet's own page, exactly as if you'd opened it alone. It's one reading surface over your real pages, not a copy.
• Click a sheet's name on its divider to open that page on its own; ✕ Exit Longform in the masthead (or navigating anywhere) returns to normal one-page editing.
• Folding works inside each sheet, links work everywhere, and the format bar follows whichever sheet the caret is in.
• Pages that can't take part (plain-text, file, and encrypted pages) are skipped.

Writers coming from Ulysses will recognise this as glued sheets; Scrivener folk, as Scrivenings. Your wiki pages just learned the same trick.

Side by Side — a second editor

The same machinery, turned sideways: two pages as two columns, both fully editable. Run Open Side by Side… from the command palette and pick the page for the second column (recent pages lead the list) — or, if you already have the read-only split pane open, click its ✏ button to promote it to a real editor.

• The caret decides which page you're writing in. Click into either column and type — formatting, links, folds, everything follows the caret. Each column saves to its own page, always.
• Click a column's name to open that page alone; ✕ Exit side by side (or navigating anywhere) returns to the single editor.
• Each column scrolls on its own — hold your place in one while you write in the other.
• When to use which: the split pane (see Transclusion and Split View) is a live viewer — perfect for watching a page you're linking to. Side by Side is for when both pages are being written: notes beside a draft, this week's plan beside last week's.
