If you mean during playback this is what Articulate have for their accessible controls
Slide Controls
The play/pause button, seekbar, and replay button are semantically grouped for screen reader navigation. Learners can use the Tab key to access each control individually and activate each one using these keyboard shortcuts:
- Spacebar: Plays and pauses the timeline; replays the slide when the timeline has ended
- Home/End: Jumps to the beginning or the end of the timeline
- Arrows: Jumps backward or forward in 0.1-second increments
- Page Up/Page Down: Jumps backward or forward in 1-second increments
Screen reader users can operate the seekbar as a slider interaction with standard controls.
