I was wondering if there is a way to do this:
I say, "TV guide"...the tv guide displays on the tv.
But I want to keep everything under "TV". So, then I can say, "record", "info", "select"...etc...without having to say, "TV record".."TV info"...etc.
This should keep the subcommands available until I say, "TV exit"...
and I don't want to have just "select", etc. as commands, because they could be used in other applications.
