Function keys in UX
The UX version does not have shortcut keys in it like the smart client.
Smart client is built for the Windows platform and we use the technology available in Windows to build the shortcut keys.
UX is browser-based and can be run in multiple browsers. More importantly, UX is device independent. This means that the interface must be standard across a Windows PC, iPad, android phone, and other devices.
Using F9 as an example, it is not available to all those devices so shortcut keys are not supported in our UX standards.
