If you are using Classic Design or SAP Signature Design, have selected accessibility mode, and have started SAP Logon/SAP Logon Pad again, the tree structure on the left-hand side of the Options dialog box is now shown in a simplified way. Only this display is accessible by default for screenreaders. This display is also selected automatically if the Options dialog box is accessed using the screenreader JAWS.
