Give your pages a color-coded identity. A page type is a category you define — Person, Project, Idea, Reference, whatever you think in — each with a color and an optional emoji. Assign one to a page and it gets a visual identity that follows it everywhere: a colored dot in the sidebar, and — the real payoff — its node glows in that color in the Graph, so your map reads as clusters of meaning at a glance.
Above the editor, in the top-left corner, is a + Type pill. Click it to open the picker:
You can also right-click a page in the sidebar and choose Set Type… — handy for typing a page you're not currently looking at.
In the picker, hover any type and a ✎ appears. Click it to rename the type, recolor it, or Delete it. Recoloring updates every page of that type at once; deleting a type clears it off every page that had it. Types live in the document, so they travel with it when you share or back it up.
Typed pages light up in their color on the map — instant visual clusters. To spotlight just one type, open the Graph's Lens… menu and pick it under Page type: those pages stay lit while the rest dim, answering “where is all my X?” at a glance. The Graph's corner legend reminds you the colored dots are types. See The Graph.
A reader asked why some pages carry a small mark in the sidebar and others do not, and why a page clipped from the web sometimes has one. The mark says what KIND of page it is, and only when there is something to say — an ordinary page you wrote has none, because “a page” is the thing that needs no label.
| 🔒 | locked with a password. This one wins over everything else, including an icon you chose, because it is the one thing you should never have to look for. |
| 📄 | a file that lives in the wiki — a PDF, a Word file, an image. You read it here and search inside it. |
| 📖 | the same, for an ePub book. |
| ✦ ✧ ❖ | written with a model’s help: an index it built, a page it drafted, a synthesis it wove from several of yours. |
| 🗺 ≣ ◫ ⊨ | a canvas, an outline, a storyboard, a mindmap — the page types you cannot tell from a name alone. |
Why a clipped page sometimes has one and sometimes does not. Clipping can bring a page in two ways. Read as an article, it becomes writing you can edit, and writing has no mark. Saved whole — the page exactly as it stood — it is a FILE, and files carry 📄. Which one you get is set in Settings ▸ Web Clipper, so a mixture in your sidebar is a record of having changed your mind rather than anything going wrong.
An icon you set yourself always wins, apart from the lock. Right-click a page and choose Set Icon… to give it one.
