We are currently evaluating a custom, simplified HTML Editor developed for and with Technische Zentrale @UR.
In collaboration with members of the TZ@UR we have developed a simple text editor for facilitating the conversion of their current directions for visitors with impairments to tabbed navigation.
The editor converts a simplified internal markup into a two-level tabbed navigation structure optimized for usage on touchscreen devices. The current state of development can be tested at: http://185.16.61.29
