    SAW - Special Access to Windows

    SAW - Special Access to Windows - a programmable on-screen keyboard.

    SAW - Special Access to Windows - is a programmable on-screen keyboard. It is a powerful tool for providing Access to the Windows operating system for people who need alternative Switch or Pointing device input options. The latest SAW 6 version update was supported by the AEGIS project (http://www.aegis-project.eu/). It is fully Windows 7-10 compatible, supports Unicode, includes its own "Blade" word prediction and abbreviation expansion engine, can interact with the CCF-SymbolServer for graphic symbol support (http://www.conceptcoding.org/), and adds several other features to make creating interfaces easy for those who use alternative inputs. Note (February, 2019): We are experiencing problems with recent MS DotNet updates breaking backward compatibility which is blocking new installations of SAW 6, and stopping the Blade word prediction from working in installed SAW 6 packages. We are working on solving this problem ASAP. Sorry for the inconvenience!
