CS,
After reading your reply and re-reading the Sonar help files on Key Bindings, I think I understand what's going on. Bear with me while I re-state a few things.
In my original post, I asked how to get the AT to send SHIFT-X to Sonar so that I could use the AT to control the Sonar X-ray feature. Referencing the SHIFT-X key was a mistake. What I should have asked is why can't I set up an AT user function key to control the X-ray function.
When I open the Sonar/Options/Key Bindings list, I see a long list of functions that I can trigger using keys or MIDI notes. The list is organized into several sections: Menu Commands, Extra Commands, CAL Program Files, Global Layout Files, and StudioWare Files.
From what I see, the AT user function supports only the "Menu Commands" section. Can you confirm this?
If this is the case, I'd like to see the AT support the "Extra Commands" set. It includes 70 commands, like X-ray, that are really useful. The other sections aren't that useful.
