Sidebar

the page tree, the sections a reader shuts, and what the browser remembers

The sidebar holds the whole wiki, with the site's name and the search box above the page list.^[1] The sidebar is exactly the window's height and never scrolls as a whole: only the list beneath the search box scrolls, and scrolling it never moves the article.^[1] The rest of the layout is described on Layout.

Page tree

Pages beneath another hang from it as a tree.^[2] The sidebar marks where the reader is: pages above the current one are bold, and its tree lines take the link color.^[3] A page far down a long list opens with its own link in view.^[4] Lines across the sidebar set off the logo, the search box and each section, whose name is in capitals, and the scroll bar sits at the edge.^[5]

Sections

A section's name is a button across the full width of the sidebar, with a mark at its right that turns as the section shuts.^[6] Pressing it slides that section's pages up or down.^[7] A shut section is out of reach of the keyboard as well as out of sight, so tabbing through the sidebar walks past it.^[7] The button beside the search box shuts every section at once, and opens every section once all of them are shut.^[8] No section may go without a name, and no two may share one, because the name is what a section is remembered by.^[9]

Storage

The sections a reader shut are stored in their browser under a key carrying the site's name, so two wikis published at one address remember their own.^[10] They are applied before the sidebar is drawn, so a reader never sees a section opening or closing as a page arrives.^[10] Where the page list was scrolled belongs to the browser tab rather than the device, and the list opens where the reader left it.^[11]

Following a link straight to a page opens the section that page sits in, whatever was stored, and stores nothing — so one shared link cannot undo what the reader chose.^[12] Reloading is not arriving: a section just shut stays shut.^[12]
