Tags

Neuron supports Twitter like tags. Tags are added by prefixing them with #, and they can appear anywhere in the note text. For example:

Gaslighting is enabled by the victim's #cognitive-distortion without which the
victimizer is rendered powerless to influence their victim.

In the above example, the note is tagged with #cognitive-distortion which also links to the tag page.

Tags can also be specified in the Zettel metadata block. The above tag can be specified alternatively as follows:

---
tags:
  - cognitive-distortion

Hierarchical tags

Tags can be nested using a “tag/subtag” syntax, to allow a more fine-grained organization of your Zettelkasten, especially when using advanced queries as shown in Tag Queries#.

For example, the following zettel is tagged “math/calculus/definition”

---
tags:
  - math/calculus/definition
---

# Derivative

It will be included in the following tag queries:

math/**
math/calculus/*
math/calculus/definition
**/definition

See Tag Queries# to understand how to link zettels automatically based on tag patterns as above.

Tag Queries
- Neuron supports tag link queries that can be used to dynamically create links based on a tag (see Tags#).
- Queries can also link to zettels whose Tags# match a glob pattern. Two kinds of patterns in particular are noteworthy:
Linking
- If you are using the Tags# plugin, you can link to multiple zettels matching a tag (see Tag Queries#).
Folgezettel Links
- Here, the # is placed at the beginning of the link; thus, the linked zettel (“Functional Programming”) becomes the parent of the current zettel (“Haskell”). Notice that, conceptually, this is equivalent to tagging; i.e., #[[Foo]] is semantically equivalent to #foo. Thus, the use of folgezettel links can obviate Tags# for most typical use cases.
Directory Tree
- Tag every zettel with hierarchical Tags# (root/**) corresponding to its path
- In addition to creating automatic a Folgezettel Heterarchy for each directory, the plugin also Tags# the notes with their on-disk path, up to, but not including their own ID. So the note at ./Home/HomeProjects/HouseWarming.md would get the hierarchical tag #root/Home/HomeProjects. These tags always start at the #root tag.

Zettel metadata#
- Zettels can be pinned in Impulse so that they appear at the top. To pin a zettel, add the “pinned” tag (see Tags#) to it.
- The metadata key tags or keywords can be used to specify tags, although neuron supports inline tags as well (see Tags#).
