+;;; Commentary:
+
+;; This package is a Corfu extension, which adds mouse support if enabled
+;; via `corfu-mouse-mode'.  Known limitations: The mode does not work on
+;; Windows.  On the terminal `xterm-mouse-mode' needs to be enabled, but
+;; clicking is still not working.  Improvements welcome!
