Leyla, Elvin and Aysel are preparing a project together on the historic buildings of Baku. If they email the file back and forth, they will soon be lost among project_final.pptx, project_final2.pptx and project_REALLY_final.pptx. On top of that, one student in their class has low vision, and the slides must work for her too. In this lesson you will learn PowerPoint's tools for teamwork and accessibility.

Sharing and co-authoring

  1. 1
    Save the file to the cloud

    For co-authoring, the presentation must live on OneDrive or SharePoint. Save it there with File › Save As — the AutoSave switch turns on automatically.

  2. 2
    Invite people

    Click Share at the top right, type names or email addresses, choose a permission — Can edit or Can view — and click Send. Or use Copy link to get a link and send it yourself.

  3. 3
    Work together

    Everyone can open the file at the same time. Pictures of the people working appear at the top right, and colored markers next to the thumbnails show who is on which slide. Other people's changes reach your screen within seconds. It works best when each person edits their own slides.

Comments let you give feedback without touching the text. Select an object or slide and click Review › Comments › New Comment (Ctrl+Alt+M). Type @ and pick a teammate's name, and they get an email notification. When the issue is sorted, choose Resolve thread in the comment's menu. All comments are in the pane that opens with the Comments button at the top right.

Accessibility: slides for everyone

Your presentation will also be seen by people with visual or hearing impairments, by people on a phone and by people in the back row. People with low vision use screen readers — programs that read the slide aloud. A screen reader can only “see” what you give PowerPoint: titles, alt text and the reading order.

Definition
Alt text (alternative text)

A short text that explains what a picture, icon or chart shows. A screen reader reads it aloud. Right-click the object › View Alt Text… (or Picture Format › Accessibility › Alt Text). For purely decorative lines and shapes, tick Mark as decorative.

  1. 1
    Run the checker

    Choose Review › Accessibility › Check Accessibility. A list of issues opens on the right: Errors, Warnings and Tips. The status bar also shows Accessibility: Investigate or Accessibility: Good to go.

  2. 2
    Fix the issues

    Click an item in the list — PowerPoint selects that object and offers a fix under Recommended Actions. The most common issues: Missing alternative text, Missing slide title, checking the reading order and hard-to-read text contrast.

  3. 3
    Check the reading order

    On the arrow of Check Accessibility, choose Reading Order Pane. A screen reader reads objects in the order of this list, and the title should come first. Drag items to change the order.

Key points

  • For co-authoring the file must be on OneDrive or SharePoint; Share sends invitations with a permission.
  • Comments: Ctrl+Alt+M; @name notifies that person; when done, Resolve thread.
  • File › Info › Version History lets you open and restore an earlier version.
  • Give every meaningful picture alt text and mark decorations with Mark as decorative.
  • Review › Accessibility › Check Accessibility finds untitled slides, pictures without alt text and weak contrast.
