Key 8 is the latest in the Key Series devised By Marion Stanton. They are aimed at the AAC user who has fairly good cognitive skills but difficulty with access. Key 8 is an improvement on Key 6 as there is more flexibility to have command buttons in addition to vocabulary buttons on each page without making the individual cells much smaller. The focus is on spelling but there is an efficient word prediction system and there are pages for symbol based communication which can be further developed really easily using the auto content feature.
