Accessibility Tray Apps in IGEL OS 12

IGEL OS 12 includes two accessibility tray apps. The general accessibility tray app is enabled by default to individually manage and configure accessibility settings. The screen magnifier tray app appears only when the screen magnifier is activated and allows to control the screen magnifier feature.

Information for Administrators

The system tray and most of the tray apps are available to the users by default.
You can enable and disable the system tray and the tray apps under User Interface > Desktop > Taskbar Items. For details, see Taskbar Items in IGEL OS 12.
The access to tray apps on lockscreen is configured separately under User Interface > Desktop > Screenlock / Screensaver > Taskbar. For details, see Taskbar in Locked Screen in IGEL OS 12.
The configurations in the tray app might slightly differ from the configurations available in IGEL Setup. IGEL Setup remains the place for administrators to set the framework for their end users (e. g. access to tray apps or starting sessions). The tray apps are designed for end users to make individual adjustments as needed.

Accessibility Tray App

The accessibility tray app provides a central place to adjust IGEL OS 12 for improved readability, visibility, and input control. From here, you can configure themes, color filters, screen magnifier and screen reader, as well as mouse and keyboard behaviour. Each area includes a reset icon in the top-right corner to quickly revert to the default configuration.

In the field Base Color, it is possible to enter a color code in HTML hex format to set a custom base color, e. g. #000000 to display black.

In IGEL Setup, you can use a color picker to design individual base colors. For more information see Themes.
