Editing X Window System (section)

===Computer accessibility related issues===
Systems built upon X may have [[computer accessibility|accessibility]] issues that make utilization of a computer difficult for disabled users, including [[right click]], [[double click]], [[middle click]], [[mouse-over]], and [[focus stealing]]. Some X11 clients deal with accessibility issues better than others, so persons with accessibility problems are not locked out of using X11. However, there is no accessibility standard or accessibility guidelines for X11. Within the X11 standards process there is no working group on accessibility; however, accessibility needs are being addressed by software projects to provide these features on top of X.

The [[Orca (assistive technology)|Orca]] project adds accessibility support to the X Window System, including implementing an API ([[AT-SPI]]<ref>{{cite web|url=https://wiki.gnome.org/Projects/Orca |title=Orca |website=GNOME Wiki! |access-date=7 November 2012 |url-status=live |archive-url=https://web.archive.org/web/20131225193528/https://wiki.gnome.org/Projects/Orca/ |archive-date= Dec 25, 2013 }}</ref>). This is coupled with GNOME's [[Accessibility Toolkit|ATK]] to allow for accessibility features to be implemented in X programs using the GNOME/GTK APIs.<ref>{{cite web|url=http://developer.gnome.org/atk/unstable/ |title=ATK - Accessibility Toolkit |website=GNOME Developer Center |access-date=7 November 2012 |url-status=live |archive-url=https://web.archive.org/web/20130101162725/http://developer.gnome.org/atk/unstable/ |archive-date= Jan 1, 2013 }}</ref> KDE provides a different set of accessibility software, including a text-to-speech converter and a screen magnifier.<ref>{{cite web |url=https://www.kde.org/applications/utilities/ |title=Utilities - Accessibility |publisher= KDE |access-date=6 January 2013 |url-status=live |archive-url= https://web.archive.org/web/20130114101752/https://www.kde.org/applications/utilities/ |archive-date= Jan 14, 2013 }}</ref> The other major desktops (LXDE, Xfce and Enlightenment) attempt to be compatible with ATK.
