Wanted to mimic the "Annular motion" of the planetarium instrument, where the stars remain fixed, but the Sun and Moon move across the Zodiac along the ecliptic. Googled Stellarium move sun moon fixed stars and so on, finally hit upon the setDate("+1 days sidereal")function, which moves the time ahead by one sidereal day, i.e. stars will be at the same spot. Keyboard shortcut Alt + + and Alt + -
