Use Slack with a screen reader

You can use a screen reader to navigate conversations, read messages, and access information in your sidebar from the Slack desktop app and Slack in a web browser.

Tip: Slack offers keyboard shortcuts for many common actions you may need to take. To view all keyboard shortcuts, press ⌘+/ (Mac) or Ctrl+/ (Windows/Linux).

Overview

Slack behaves more like an application than a webpage. We recommend that:

• NVDA and JAWS users primarily navigate around in Focus/Forms mode instead of Browse mode.
• All screen reader users use Slack’s desktop application rather than a web browser if possible.

When exploring Slack, there are a few important concepts to understand:

Workspaces	A Slack workspace maps to an organization or a department—think of it as an office building that you need to be invited into. The Slack desktop and mobile apps allow you to sign into multiple workspaces at once.
Channels	Channels are like large conference rooms or offices inside the office building, and can be created for any project, topic, or team. Channels can be public, meaning anyone in the workspace can read or join, or private. Channel names always start with a # (pound sign or hashtag).
Direct Messages	Direct messages (also known as DMs) are smaller conversations in Slack that happen outside of channels. DMs work well for one-off conversations that don’t require an entire channel of people to weigh in, like if you wanted to ask a coworker to reschedule a meeting. You can DM a single person, or several people at once.
Conversations	Channels and direct messages are structured similarly in Slack. We refer to them jointly as conversations.
Threads	Threads help you create organized discussions around specific messages within a conversation.
Mentions	Mentions are a direct way to notify people of something that needs their attention in Slack. They start with an @ (at symbol).
Reactions	An emoji reaction can be attached to a message to replace the need for a follow-up message. You can add multiple emoji reactions to a message.

Navigating Slack

Slack’s interface is anchored around a main window, made up of several top-level sections. You can navigate between these sections by pressing F6, and within each section using Tab and the arrow keys. All toolbars in Slack are navigated with the arrow keys.

It’s possible to open separate windows in Slack for specific tasks, such as reading and replying to a conversation or thread, participating in a huddle, and viewing and editing a canvas.

Tip: Mac users can also use ⌘+Ctrl+← / → instead of F6.

Note: If you're using Slack in a browser, press ⌘+F6 / ⌘+Shift+F6 (Mac) or Ctrl+F6 / Ctrl+Shift+F6 (Windows).

Top-level sections

The section names and roles of the main window of Slack are listed here in the order the screen reader will read them out:

History and Search toolbar	Home to the options for navigating through your browsing history, search, and help.
Tablist	Allows you to switch between modes of working in Slack (see the Tablist section below for more).
The workspaces tablist (if you are signed into multiple workspaces)	Allows you to switch between workspaces that you’re signed in to. The workspace tablist can be hidden or revealed using the ⌘+Shift+S (Mac) or Ctrl+Shift+S (Windows) shortcuts.
Navigation area	Each tab has a navigation area that you can browse through to open specific conversations, messages or files in the primary view.
The primary view	Every tab in Slack has a primary view, where you interact with conversations and reply to messages. In some tabs, you’ll see an empty state in your primary view
The secondary view (if you have it open)	Secondary views are opened when diving into something in the primary view, such as an individual thread within a channel, or a user profile.
Control strip	Home to the user menu and the compose/create new button. When you’re invited to a huddle, you’ll also see the alert banner and huddle mini player here.

Tablist items

Each page in your tablist will have a slightly different layout, but generally, you can expect to use the Navigation area to open up a conversation in the primary view. Each tab’s unique navigation experience is described further down this page.

Home	Ctrl + 1 (Mac) Ctrl+Shift+1 (Windows)	Browse, organize, and interact with all channels you’re a member of. You can also review all unread messages using the Unreads page.
DMs	Ctrl+2 (Mac) Ctrl+Shift+2 (Windows)	Review your list of your active direct message (DM) conversations.
Activity	Ctrl+3 (Mac) Ctrl+Shift+3 (Windows)	A filterable, chronological feed that includes mentions, replies to threads you’ve participated in, reactions to your messages, invitations to channels, and app notifications.
Later	Ctrl+4 (Mac) Ctrl+Shift+4 (Windows)	A place to organize and respond to work you’ve set aside for later. Set reminders and mark tasks as complete.
More	Ctrl+0 (Mac) Ctrl+Shift+0 (Windows)	A menu for additional browsers in Slack. When the Slack window is resized to be very short or your zoom level is higher than 100%, More acts as an overflow menu for any tabs that no longer visually fit on screen.

You’ll always find the following browsers in More, even if Slack is in full-screen:

• Automations 
• Huddles 
• Canvases 
• Your organization (channels, people, and files)
• External connections 

Navigation tour

To understand how all of this works together, we’ll take you through a brief tour of two tabs: Home and Activity. These tabs represent the different navigation experiences you'll find in the Slack app on desktop.

  Home

When you open Slack, the Home tab is open by default.

1. To navigate to Home or any other tab, press F6. 
2. Select   Home from the tablist, then press Enter. 

The Home tab is where you'll interact with the majority of messages in Slack, and you can do so by selecting channels or the Threads, Unreads and Drafts & sent pages.

The Navigation area for the Home tab consists of a list of all the channels you’re a member of, which can be organized into sections.

1. Use the ↑ or ↓ arrow keys to navigate through the list of channels and sections to hear their names, and information such as whether the channel or section has any unread messages.
2. Use the ← or → arrow keys when your focus is on a section header to expand or collapse the section.

With your focus on a specific channel or conversation, you can use the context menu to access more information or actions related to that channel.

1. To open the context menu for a channel, right-click the channel name in the sidebar.
2. With your focus on a channel, press Enter to open the channel in the primary view and interact with the messages there. 
3. When you open a channel in the primary view, your focus will be placed in the message composer of that channel, where you can send a message or use the ↑ or ↓ arrow keys to read through the conversation.

For more on navigating a conversation, jump to the participate in a conversation section.

  Activity

The Activity tab organizes the mentions, thread replies, reactions and notifications that you can reply to.

1. To navigate to Activity or any other tab, press F6.
2. Select   Activity from the tablist, then press Enter to open the tab.

When you open the Activity tab, your focus will land in the Navigation area, which is a filterable list of your notifications in reverse chronological order.

1. Use the ↑ or ↓ arrow keys to navigate the list.
2. Press Shift + Tab to move to the controls to filter items in the list by activity type or to only show unread notifications.
3. When any item is in focus, open the context menu to access actions such as opening the conversation in a new window, or saving it to the Later tab.
4. Press Enter to open the in-focus item in the primary view, while keeping the navigation area open so that you can easily address the next item in the Activity tab.

Useful keyboard navigation

Open previous or next item

• In any tab, use Option+↑/↓ (Mac) or Alt+↑/↓ (Windows) to open the previous or next item in the navigation area.
• In the Home, DMs, or Activity tabs, press Option+Shift+↑/↓ (Mac) or Alt+Shift+↑/↓ (Windows) to open the previous or next unread item in the navigation area.

Summarize activity from all workspaces

To get a summary of notifications from each workspace you’re signed into, press ⌘+Option+S (Mac) or Ctrl+Alt+S (Windows) on your keyboard. The summary will read out a count of notifications and unread messages, depending on where you have unread activity:

• Unread activity in your active workspace
  "[Number of] notifications and [number of] unread messages in [name of active workspace]."
• Unread activity in your active workspace and other signed-in workspaces
  "[Number of] notifications and [number of] unread messages in [name of active workspace], and [list of other signed in workspaces] have notifications."

Switch between workspaces

You can jump to the workspace menu by pressing ⌘+Shift+S (Mac) or Ctrl+Shift+S (Windows), then use ↑ or ↓ to navigate to the workspace of your choice. You can also navigate to the workspace switcher menu using F6 navigation.

Jump to any conversation, tab, or page

The easiest way to open a channel, DM, tab (ex., Home, DMs, etc), or page (ex., Unreads, Threads, Drafts & sent) is with a keyboard shortcut.

1. Press ⌘+K (Mac) or Ctrl+K (Windows/Linux).
2. Type the name of a channel, person, or page.
3. Press Enter.

This shortcut can be used from any tab in Slack. Channels will always open in Home, and direct message conversations will open in either the Home or the DMs tab.

Tip: You can use the Alt/Option+↓, Alt/Option+↑, shortcuts to navigate to the previous or next conversation in your sidebar.

  Read messages chronologically from oldest to newest. The initial point of focus will be the first unread message in a conversation. If all messages are read, the focus will move to the last message you focused on in the conversation. Press ↓ to read the next message.
• Start me at the newest message, and mark the channel read
  Read messages in reverse chronological order. The initial point of focus will be the most recent message in the channel.
• Start me at the newest message, but leave unseen messages unread
  Read messages in reverse chronological order. The initial point of focus will be the most recent message in the conversation, but the conversation will remain marked as unread until you’ve read every message.

Note: To choose whether sounds are played when you send or receive messages while inside a conversation, navigate to the Notifications section of your preferences.
