# Readwise Reader Documentation > This document contains all documentation content from Readwise Reader, providing comprehensive information about features, guides, and frequently asked questions for the Reader app. This file includes 45 documentation pages. ## Action Tags ## What is an Action Tag? Action tags are highlight notes that use a specific syntax to perform actions on the associated highlight. All action tags begin with a `.` character, and their functionality effects how the highlights appear in Readwise. ## How can I create headings between my highlights? In Reader, headings are added to the Notebook view (`Shift + 1`) automatically when they’re detected within the document’s content. However, if you want to see those headings in Readwise as well, you’ll need to use an action tag. To do so, highlight the text that you want to appear as a heading, then add a note (`N`) with the text `.h1`. This will create a top-level heading with the text of the highlight. To create nested headings, you can use an `.h2` tag and so on. Note that you can start with lower level headings (e.g. `.h3`) and they’ll still appear in Readwise, but for the table of contents to appear on the left side of the page, you’ll need to start with at least one `.h1` tag. ## How can I combine two disparate pieces of text into a single highlight? Oftentimes, the most salient parts of a paragraph are the first and last sentence, which can be frustrating when the author includes a bunch of fluff in between them that just bog you down when reviewing the highlight later. To fix this, you can use the concatenation action tag. Simply add a note (`N`) with the text `.c1` to the first highlight, then `.c2` to the next highlight. When the highlights sync to Readwise, they’ll appear as a single highlight with an ellipse (`…`) between the two pieces of text. You can string as many highlights together in this way as you’d like by continuing on to `.c3`, `.c4`, etc. A tag of `.c1` will always begin a new concatenation string. ## How can I create a Q&A mastery card while reading? You can use action tags to create a Q&A [mastery card](https://readwise.io/mastery) in Readwise associated with a particular highlight. To do so, add a note (`N`) to the highlight using the syntax `.qa [QUESTION?][ANSWER]`. ## Can I add a regular note to a highlight with an action tag? Yes! To add a note to a highlight that has an action tag, simply add a line break after the action tag. You can do this by pressing `Shift + Enter` in the note field (`Enter` by itself will save the note). For example, if you wanted to add a brief description of a section’s content with a heading, you could do something like `.h1 ⏎ This section is about how Topic A relates to Topic X.` The note text will then appear below the heading in Readwise. --- ## Adding Content to Reader ## What's the difference between Library and Feed? Reader has two broad sections: Library and Feed. Library is further subdivided into a handful of locations like Inbox, Later, Archive, and Shortlist (depending on your Library configuration). Library is where things go that you manually curate for yourself and choose to save permanently, such as articles saved from the browser extension or uploaded EPUB documents. The [Feed](/reader/docs/faqs/feed) is where things go that are automatically pushed to you, such as RSS feed content, and it's divided into two locations: Unseen and Seen. As you find documents in Feed that you want to read later and/or permanently save, you can move them to your Library. ## How do I use the browser extensions to save articles to Reader? The Reader browser extension performs two functions: first, saving articles to Reader and second (optionally), highlighting the open web. To save a document to Reader, tap the icon in the browser bar or use the keyboard shortcut `alt + R`. (You can change the keyboard binding in the extension's options.) This will save a clean, readable version of the document to […gekürzt]
