**Power tags** are an advanced feature which can add extra functions and layout options to your wiki pages (and sometimes research notes). They are entered like regular tags but follow the format `key:value`. After adding a power tag, you must refresh the page.
To add tags, look for this box at the bottom of a wiki page or research note:

### For Educators:
* Visit this page to learn how to post your assignment, and have student submissions grouped with it: https://publiclab.org/wiki/requesting-responses
### General power tags
* `events:foo` displays a listing of research notes tagged with "event" and "foo", and a link to post new notes with those tags in the left sidebar.
* `sidebar:featured` displays "featured" links and images in the sidebar instead of the usual "related content"
* `sidebar:none` hides the sidebar
* `style:presentation` hides the wiki toolbar (with Edit, Talk, Revisions) for more formal pages, and makes the lead image of wiki pages full-width
* `style:minimal` just hides the wiki toolbar (but it's accessible via a small caret button)
* `style:wide` removes the 800px width limit from wiki pages, and allows them to flow full page
* `style:fancy` is used to style articles from the GrassrootsMappingForum
* `style:nobanner`
* `parent:foo` adds a bar that links back to a parent wiki page
* `with:username` adds a co-author to your research note with a live link to the user's profile page, however, the note itself will not show up under that user's profile.
* `lang:es` or `iso:es` is the way to indicate language in a research note or event. In this example, `es` indicates Spanish.
* `locked` -- locks a wiki page from edits except to moderators and admins. An atypical power tag in that it doesn't follow `key:value` format; [documentation here](https://publiclab.org/wiki/locked)
* `redirect:____` -- redirects a page to the page with the specified ID -- i.e. `redirect:100` would redirect to node 100. Does not affect admins or moderators.
* `series:____` -- displays a message of "This is part of a series on `tagname`." with a link to /tag/tagname
* `abtest:____` – redirects 50% of page visitors to the page of id given, such as `abtest:1234` -- for "user testing" two versions of a page. Admins and moderators not affected.
* `activity:____` -- will list the content in an activity grid set to that tag
* `question:____` -- will list the content in as a question on that tag page
* `alert:___` -- will show the feature as alert on that node.
### List of power tags useful for project or location based pages:
* `lat:41.023` and `lon:-71.023` latitude and longitude. Together with the simple tag "chapter", the combination of these three tags will create a point for your chapter [on the Places map](/places)
* `events:foo` displays a listing of research notes tagged with "event" and "foo", and a link to post new notes with those tags in the left sidebar. Especially useful where foo = the name of your chapter page.
* `list:foo` displays recent posts from a Google Group with the name "foo" and a subscription input box
* `tabbed:notes` and `tabbed:wikis` display a tabbed header which offers tabs with links of related research note and wiki content
* `notes:foo` displays 4 recent "popular" research notes tagged "foo" (in grid view, popular means >20 views) at the top of the page, under the tabs if they exist. For example see [Gulf Coast](/wiki/gulf-coast]
* `parent:foo` adds a bar that links back to a parent wiki page, especially useful for places within regions
### Alerts
You can display alerts using power tags. Admins can create new types of alerts which can be displayed on any wiki or note. An example is `alert:testing-2` -- use this tag on your page, and you'll see an example alert appear at the top of the page content (below the title).
Available alerts using this system are:
* `alert:testing-2`
* `alert:`
**Admins:** to create new alerts, [create a new Feature](/features) with the name `alert-_____` where the blank is the alert name. For example, for the tag `alert:testing-2`, the feature is named `alert-testing-2`. The text of the Feature must include the "alert" HTML too:
```
Notice This is a test.
```
### Inline power tags
You can now use "inline" power tags in the middle of a research note or wiki page. The first one is for generating a list of notes for a given tag, and is used in this format:
> `[notes:]`
For more **advanced inline tagging**, see [Advanced Grids](/n/15582)
For example, to list all notes tagged with `peru`, you can use:
> `[notes:peru]`
Wiki pages can be listed too:
> `[wikis:coqui]`
To create a button with text on top that links somewhere outside of publiclab, use:
> `[button:foo:https://www.google.com]`
The above creates a button with a "foo" on top of a button that links to Google. For a button that links somewhere on the site, you can use something like:
> `[button:foo:/questions]`
The above creates a button with the text `foo` on top that links to: "[link you are currently on, you can find this on your address bar]/questions". So if I'm on `https://publiclab.org`, this links to `https://publiclab.org/questions`.
For a more complex example, you can list all questions on the topic of "infragram" using:
> `[notes:question:infragram]`
More advanced uses like **activity grids** can be found in this post:
https://publiclab.org/notes/liz/08-30-2016/check-out-these-activity-grids
And in the [requesting responses](https://publiclab.org/wiki/requesting-responses) documentation.
### Inline People Lists
`[people:organizer]` -- will display any people tagged as organizers. Add profile tags on your profile page (admins can do this for anyone)
Example:
[people:organizer]
### Inline Maps
Maps may be embedded inline, displaying content tagged with `lat:___` and `lon:___` location tags. Read more [about inline maps here](/wiki/inline-maps).
### Inline graphs
This feature is still in testing, but allows display of a CSV file as a graph:
`[graph:/i/25356.csv]` will display:
[graph:/i/25356.csv]
****
### Prompts
Prompts let us offer a place on a wiki page where a reader can enter text and it's directly inserted into the text of the wiki page just above the prompt.
`[prompt :text:Placeholder text]` (without space after `prompt`)
That looks like this when saved:
[prompt:text:Placeholder text]
We can also ask for longer-form text input with the keyword `paragraph` -- but be aware that the "placeholder text" can only hold letters, numbers and spaces -- no punctuation (yet):
`[prompt :paragraph:Placeholder text]` (without space after `prompt`)
That looks like this when saved:
`
[prompt:paragraph:Placeholder text]`
Two identical prompts on one page can cause trouble, but if you add a unique id, you can get around that:
`[prompt :text:Placeholder text:UNIQUE-ID]` (without space after `prompt`)
The prompts are [better documented here](https://jywarren.github.io/short-code-forms/examples/).
There's also this type of "edit here" prompt:
> `[ edit ]` (but without spaces)
Which generates this type of prompt:
[edit]
****
### Automated power tags, not for manual adding
You might see some of these being generated automatically, like when checking the box for a Research Note to be an "Event" or a "question" or when awarding Barnstars to someone's Research Note. Don't manually add these:
* `event:rsvp` `date:YYYY-MM-DD` `rsvp:username`
* `barnstar:barnstarname`
* `question:foo` `response:foo`
### Tag aliasing
_This feature is for admins only -- please contact web@publiclab.org with questions._
We've created a system for aliasing tags, which serves a number of purposes:
A) **disambiguation** -- we have both `spectrometer` and `spectrometry` -- as of recently, we'd prefer `spectrometry`. So we make each the alias of the other, and the two become somewhat (but not completely) interchangeable on the site.
1. When looking at https://publiclab.org/tag/spectrometer, you see content tagged with `spectrometry`, and vice versa.
2. Email notifications do not yet take advantage of aliasing, but may at some point (see below).
B) **subcategories** -- `multispectral-imaging` contains and is broader than `infragram`.
1. When looking at https://publiclab.org/tag/multispectral-imaging, you should see content tagged with `infragram`.
2. When looking at https://publiclab.org/tag/infragram, you should **NOT** see content tagged with `multispectral-imaging` -- your query is more specific than that.
**Later goals:**
Some aliasing features are more complex and not complete yet.
**Email subscriptions** - when people subscribe to a tag, they should receive emails when content is posted using a tag that is a (more generalized) alias of the subscribed-to tag.
