If you have an MX-850 or lower, you can't. If you have an MX-900 or higher, you can use the IR Database Navigator to drag in individual commands. If you are using an MX-850 or lower, you can create a new device, bring in all of the IR database commands for your TV, then use a shortcut from your TV device to access the commands you want. Otherwise, the way to do it would have been to start with all the IR database commands, then erase the ones you don't want/need and replace them with learned commands.
