Hi Tamas,
This seems a valid business case for me and SAP personas product team needs to be notified about this. Also do we have a feature suggestion page, which I think is needed a lot for this technology more than any thing as some times we are really struck and there are no possible other ways.
Hi Sunit,
I have a vague suggestions for you to research if this feature is a blocker for you.
1) edit the personas index page, /sap/bc/bsp/persos/mainapp/index.html add a script that listens to f8 and block it right there. You can't propagate the even to personas as there is silverlight in between and you can't access personas DOM.
Try it, it might or might not work though.
Thanks,
Bhaskar
