Canvas Navigation with a Screen Reader
Canvas makes extensive use of ARIA landmark regions. Accessible Rich Internet Applications (ARIA) defines ways to make web content and web applications more accessible to people with disabilities. Therefore, the best way to get around in Canvas is to navigate via regions. Within regions, Canvas uses HTML headings, so navigating between headings can be helpful.
When using a screen reader, the Canvas page navigation menu is as follows:
- Main navigation
- Context navigation
- Breadcrumbs navigation
- Main region
- Complimentary information
- Content information
Canvas-wide Accessibility Components
Canvas contains several unifying accessibility features that can be found on various pages in Canvas.
Moving Content within Canvas
Wherever drag and drop is used to reorder components, the Move-to option is also available and allows both screen readers and keyboard users to move Canvas content. The Move-to option is available in the following features:
- Course Navigation
By pressing the comma key, users can view a pop-up window with shortcuts for keyboard navigation. Keyboard shortcuts are available on the following Canvas pages:
- Assignments Index Page
- Course Settings: Navigation Tab

Accessibility within Specific Canvas Features
Several areas within Canvas have been specifically improved for accessibility. Other features may be limited at this time. This section highlights several feature areas and accessibility behaviors.
The Canvas interface uses rem sizing for fonts so any typography will meet the following: it will zoom when the browser is zoomed, and it will scale if a custom browser-sized font is chosen or set from a browser's setting.
