Barbara Welsford, our Assistive Technology Specialist here with SSRCE, created two helpful YouTube videos. The 1st video can assist a user of RW4G if they seem to have greyed-out tools, but should have an active license. The 2nd video can help when the TextHelp PDF Reader doesn't launch as expected for reading PDF documents aloud, which are located in your Google Drive.
TIP: BOTH videos were created with Closed Captioning available (CC). SAVE both of these videos to reference later as needed.
