@ninyule First of all, many thanks for the configuration instructions for Harmony Ultimate. It worked for Harmony 650 as well.
Regarding the configuration for the Flip key, In the Keymap Editor, you mention in one of the steps “Select Action”. I don’t see a “Flip” action or I don’t know what is the Flip key called in Kodi-speak.
Also, I tried to experiment with configuring the Red-Green-Yellow-Blue buttons as shortcuts for Movies-TV-Music-Pictures in Slice. While Music & Pictures work, Movies doesn’t do anything apart from the usual system sound for a keypress and TV takes me to PVR. Can you help with these?
