Links are what turn a pile of notes into a body of knowledge. In Nodes you make them inline, as you write, with the familiar double-bracket syntax.
Link as you type
To link to another note, write its name in double brackets:
I built on the idea from [[Spaced Repetition]].
As you type inside the brackets, Nodes suggests matching notes; click one to insert the link without retyping its full name - or move through the list with the up and down arrows and press Return to pick the highlighted note. Press ⌘Return instead to link and jump straight to that note. The link becomes a real connection between the two notes - not just blue text.
You can link to a note that doesn't exist yet, too. The link is ready the moment you create that note.
Renames just work
Rename a note and Nodes updates the links that point to it, so a tidy-up never leaves a trail of broken references behind. You're free to rename things as your thinking sharpens.
Why it matters
Every link you make is also an edge in your graph. The more you connect, the more the shape of your ideas becomes something you can actually see and explore - clusters of related thought, bridges between topics, notes that quietly tie everything together.
Linking is the single habit that gets the most out of Nodes. When in doubt, link it.
