Desativar Apertar / Zoom Logitech K400 Teclado Touchpad

Question

Ao rolar ou usar o touchpad no K400, o calor dos dedos ou o movimento acidental ocorrem com bastante frequência, ativando as funções Pitada e Zoom. No entanto, essas funções estão vinculadas ao código de acesso 37 (geralmente Control. Troquei Control_L por Super_L). Precisa fazer com que o touchpad pare As funções Pinch e Zoom todas juntas para não ficarem mais presas ao código 37. Ubuntu 14.04. Obrigado.
