Callouts
A callout is a coloured block inside a note for the part you don't want to skim past — a warning, a decision that's now locked, a rule you keep breaking.
Five types:
| Type | Use it for |
|---|---|
| Note | Quiet context for future you |
| Tip | Advice worth surfacing |
| Important | Something you must not lose |
| Warning | Preventing a mistake |
| Caution | A real risk if ignored |
Each type has its own colour and icon, drawn from the same palette as the rest of MLW.
Adding one
Three ways, all in the note editor:
- Slash command — type
/note,/tip,/important,/warning, or/caution. The short forms/warn,/imp,/info,/dangerand/calloutwork too. - Type it — type
> [!tip]followed by a space and the block converts as you type. - From a selection — select text first, then use the slash command to wrap what you've already written.
Titles
Every callout has a title line. Leave it alone and it shows the type name ("Warning"). Type over it and you get whatever you want:
Founding rate is permanent Grandfathered for the life of the account, not 12 months.
You can also write a title and leave the body empty. That gives you a one-line rule, which is often all you need:
Never bundle a price change with a feature launch.
Changing the type
Click the icon on the left of the callout and pick a different type. The content stays where it is — no deleting and retyping.
What goes inside
Anything a note can hold: bold and italic, inline code, lists, links, [[wikilinks]], @task mentions, #tags, and highlights. A callout is a container, not a special text box.
To get out of an empty callout, press Backspace at the start of it.
How it's stored
Callouts are written as ordinary markdown:
> [!WARNING] Heads up
> Stripe descriptor is fixed once set.This is the same syntax GitHub and Obsidian use. Two things follow from that:
- Your notes stay plain markdown. Nothing proprietary is added to the file.
- Callouts you write in MLW render as real callouts in Obsidian after exporting, and callouts written in Obsidian show up correctly in MLW.
On mobile
Callouts render on mobile too, in the same colours, in both the note editor and the Notes pane on Today. Writing one is a web thing for now — the mobile note editor is a plain markdown field, so you can type > [!TIP] by hand and it will render, but there's no slash menu or type picker there yet.
