Key Commands for Channel Settings Window...

I’m building a Lemur control for Cubase. Most everything is working great - love it. But I can’t seem to find proper key commands for setting focus in the Channel Settings window for the selected channel. I want to be able to open the Channel Settings window (got that working fine) and then navigate around in there through my lemur controller (i.e. select the equalizers tab, the inserts tab, the sends tab, etc.) Does anyone know if this is possible? I’ve scoured the key commands and can’t seem to find the correct command. Thanks so much! Steve
