BigBlueButton supports both JAWS and NVDA screen readers.
We recommend using Windows with Windows Explorer (it seems to have the best support for those products).
How does BigBlueButton interacts with a screen reader:
The typical usage of the screen reader is to use the up and down arrow keys to navigate through the User Interface.
Once BigBlueButton loads the TAB key must be pressed at least once, this will allow you to navigate the rest of the application using the arrow keys.
The BigBlueButton User Interface is broken up into 5 sections, users, webcams, presentation, and chat:
These sections can be accessed from anywhere on the page by pressing the corresponding hotkeys:
- Users: control + alt + 1
- Webcams: control + alt + 2
- Presentation: control + alt + 3
- Chat: control + alt + 4
- Closed Caption: control + alt + 5
To mitigate the amount of feedback provided by the screen reader, some of the most used tasks have been made available with global hotkeys:
Navigating through BigBlueButton using the TAB or Up and Down arrow keys to cycle through the sections can cause complications when trying to discern what is being said by the presenter, and hearing the screen reader as you navigate:
- Mute / unmute: control + alt + M
- Focus chat input: control + alt + I
- Raise your hand: control + alt + R
The following are a few of the most commonly used hotkeys within the given menu:
- Focus chat tabs : control + shift + Y
- Focus chat Message list: control + shift + R
- Send chat message: control + shift + S
- Close private chat tab: control + shift + E
The defined hotkeys change based on the current pane selected.
A listing of all available hotkey combinations defined within a given focused pane is made available by pressing the key combination: control + alt + h.
