Message composition

Mattermost is compatible with most popular screen readers, such as Apple VoiceOver or JAWS for Windows. A custom readout is composed for each message by combining the message elements and reading them together in full sentences. Message elements will read in the following order:

  1. Header: Author, timestamp, message type (i.e. parent post or reply)

  2. Main Content: The message content typed by the author

  3. Attachments: The number of attachments (if applicable)

  4. Emoji Reactions: The number of unique emoji reactions (if applicable)

  5. Saves/Pins: If a message is saved or pinned (if applicable)

For example, a message read by a screen reader may sound like the following:

Eric Sethna at 12:57pm Thursday June 13th wrote a reply "Thanks for the review", 3 attachments, 2 reactions, message is saved and pinned.

Channel sidebar navigation

When the channel sidebar region is focused, use the or arrow keys to focus individual sidebar sections, such as Favorites, public channels, private channels, and direct messages. Press Tab to navigate through channels or other buttons within a sidebar section.
