ALV Grid Accessibility in the SAP GUI for HTML

The accessibility option in the SAP GUI for HTML provides texts suitable for use with screen readers, and also provides keyboard alternatives to using the mouse. For the latest information, see SAP Note 489227.

To enable accessibility, set parameter ~accessibility to 1 in the appropriate service file or in the global service file. You can also set the accessibility parameter in the address bar of their browser when logging on. To do this, append ?~accessibility=1 after the exclamation point (!) in the URL as shown below:

<protocol>://../../../<service>/!?~accessibility=1

The following keys are relevant to the accessibility in the ALV Grid:

Key	Description
S	If pressed at the beginning of the grid, the focus jumps to the end of the grid If pressed at the end of the grid, the focus jumps to the beginning of the grid
TAB	Shifts the focus forwards to the next focus element.
SHIFT + TAB	Shifts the focus backwards to the previous focus element.
Left Arrow	Use to browse through the values in a dropdown field.
