Keyboard access

• The Tab key can be used to advance the selection and the Space key used to select.
• Up and down buttons on-screen will advance the sliders to change the number of equal parts.
• The Enter key can be used to Check Work and to move on to the next problem in a lesson.
• When a list box has focus, the up and down arrows scroll through the list.
• Some of the higher order thinking tools are not yet accessible via the keyboard. This work is in progress.

• Regarding screen contrast, we have large yellow tooltips for many of the tools now, as well as for our feedback.
• We have large red highlights around the focus objects partially implemented at this time.
• The screen colors can viewed in high-contrast using accommodations like ZoomText, or by changing the access setting on the Mac OS.

• Auditory support includes sounds for button clicks, scan sounds (tab key), correct, incorrect and checkbox select. Sounds can be enabled via Settings.

The lessons can be used through leading AAC devices by sending tab, space and number keys. The enter keys also can be used to check work. Downloadable files are available for the following devices

• PRC ECO-14 access is available through a custom .mti file.
• DynaVox Series 5 access is available through a custom .epg file.

• Two-switch scanning access works through Tab and Space. A floating number pad makes number entry available.
• Some of the higher order thinking tools are not yet accessible via the keyboard. This work is in progress.
• Single-switch scanning is a possibility we will be exploring for the future.
