Known Issues

1. People report that the keyboard shortcut Alt-Escape intended to exit full-screen mode in the TTY:, VIO: and DZLR: devices on the Desktop UI does not work under Windows and Linux as the Chrome browser or the O/S already captures this key combination. It does however work under OSX/macOS
2. The MAN: (manual) device on the Desktop UI is currently a proof-of-concept with only the pre-loaded manuals available. Additional functionality will added to allow adding and removing PDF files to/from the MAN: (manual) device
