Links, images and callouts
Link to pages and headings, add images and files, and use the five callout types.
Links
Select some text and press ⌘K (Insert ▸ Link…). Start typing a page or heading name — or paste a web address — and press Return.

- With nothing selected, ⌘K inserts a link whose text is the page’s or heading’s title.
- Type
[[anywhere in the text for the same search inline. - Links are written as paths relative to the page, with
#anchorfor a heading — for example[Rollback](../engineering/release-checklist.md#on-release-day). Anchors follow GitHub’s rules, so links work on GitHub too. - ⌘K with the caret in a link shows its card: Open, Change Destination…, Edit Text and Remove Link.
A click in a link places the caret, so you can edit its text. ⌘-click follows it. Hover a link for half a second for its card — where it goes, with Open, Edit Link, Copy (the destination as written) and Unlink. Links to web pages show ↗ and open in your browser. On a Read Only page and in Preview, a click follows a link, ⌘-click opens it in a new tab and ⌥-click in a new window.
Pasting a web address over selected text links the text to it; pasted on its own, the address becomes a link that shows the address.
A link whose page can’t be found is underlined with a red dotted line, and its card offers Choose New Destination…. When you rename or move a page in Kirbon, links to it are updated for you.
Images and files
Drag images or files from Finder onto the page, paste them, or choose Insert ▸ Image… or Insert ▸ File…. Kirbon copies each file into assets/<page>/ next to your pages — originals are never moved — and shows progress while it copies. Images appear as images; other files as file chips with their type and size.

Click an image to select it. Its toolbar has:
- Size — Fit Width, 75 %, 50 % or Original; or drag a corner handle to resize in 5 % steps;
- Alt Text… — read by VoiceOver and shown if the image can’t load;
- Caption — a line of text under the image;
- Replace…, Open Original, and ⋯ for Remove from Page, Show in Finder and Copy Image.
Press Space on a selected image or file chip to see it in Quick Look; double-click a file chip to open it in its app. ⌫ removes it from the page, ⌘C copies its Markdown.
Removing an image from a page keeps its file in assets/ — Undo brings it back. A missing image shows its name with Locate….
When a file with the same name is already in the page’s attachments, Kirbon asks: Keep Both, Use Existing File or Replace….
Callouts
Callouts are coloured boxes for notes and warnings. Kirbon saves them as GitHub alerts, so they look the same on GitHub.
| Callout | Use it for | Markdown |
|---|---|---|
| Note | Neutral information | > [!NOTE] |
| Tip | Optional advice | > [!TIP] |
| Important | Must-know information | > [!IMPORTANT] |
| Warning | Risk of a problem | > [!WARNING] |
| Caution | Risk of harm or data loss | > [!CAUTION] |
Insert one from the / menu or Insert ▸ Callout. The type button in a callout’s corner changes its type, and offers Remove Callout Style — Keep Text and Delete Callout and Its Text.
