All, I've posted another topic but got no replies, I'm thinking it wasn't clear enough. I am wondering about this issue: Accessibility in Portal
http://help.sap.com/saphelp_nw04/helpdata/en/8d/b7bf3feb915f7be10000000a11405a/content.htm
The link provides a table which states that All events are triggered by keyboard, regardless if the user has Accessibility activated on the account or not. But I find the top-level navigation not to be accessible by keyboard w/o that checked.
I would like to know whether this can be achieved or is this a known bug where future releases will have a fix. I am currently on SP14.
