My first intuition would be to do something like: (define-key input-decode-map [wheel-down] (lambda (_prompt) [])) (define-key input-decode-map [wheel-up] (lambda (_prompt) [])) (define-key input-decode-map [mouse-1] (lambda (_prompt) [])) (define-key input-decode-map [mouse-2] (lambda (_prompt) [])) (define-key input-decode-map [mouse-3] (lambda (_prompt) [])) If that works, then you'll probably want to add more bindings for those cases where you hit the "mouse" while holding a modifier, i.e. something like: (dolist (modifier '(control meta nil)) (dolist (base '(wheel-down wheel-up mouse-1 mouse-2 mouse-3)) (define-key input-decode-map (vector (event-convert-list (list modifier base))) (lambda (_prompt) [])))) - Stefan
