I just added a new command to rotate across a list of Modus themes: modus-themes-rotate . Check which is the current Modus theme and find its position in the list of the themes that are in rotation. This is a nice little command that complements the existing modus-themes-toggle (switch between two themes, per modus-themes-to-toggle ) and modus-themes-select (choose a theme from the entire family using minibuffer completion).
