Links
A Markdown link is[the words](https://the.address). The editor colours the words in the theme’s link colour and steps the brackets and the address back, so a paragraph full of links still reads as prose.
There are three ways to make one without typing the brackets:
Paste over a selection. Select some words, copy a web address from anywhere, and paste. Instead of replacing the words, ⌘V wraps them: [the words](https://…). The new link pulses once in the link colour so you can see what happened. Spaces at the ends of the selection stay outside the link; selecting an address itself, or something with a line break or a bracket in it, pastes normally.
⌘⇧K. Wraps the selection as a link. If a web address is on the clipboard it is used and the caret lands after the link; otherwise the address is left as https:// and selected, ready to type over. With nothing selected you get [link text](https://) with the text selected.
Type an address. A bare https://… is coloured as a link on its own.
Links are not clickable in the editor, where a click should place the caret. In Review they open in your browser.
Image references, , are styled the same way and shown as pictures in Review. Paths are relative to the document’s own folder in the library.
Tags
Write#tag anywhere in a document — #ideas, #draft, #2026-plans, #work/clients — and it appears under Tags in the sidebar with a count of the documents that carry it. Click a tag to filter the sidebar and All Documents to those documents; the tag’s name appears at the top of both with a small ⓧ that clears the filter (Esc in All Documents clears it too). A search and a tag filter combine.
A tag starts with a letter or an underscore and may contain letters, digits, hyphens, underscores and slashes. Something that looks like a hex colour, #FFF or #1E90FF, is left alone, and so is anything inside code.
Tags are how a note lives in more than one place without being moved: a document in Essays can carry #travel and show up beside the travel notes, with the file exactly where it was.
