Preferences for customizing delta values and default action
; '''mousewheel.with_shift.delta_multiplier_x'''
; '''mousewheel.with_win.delta_multiplier_x'''
: Customizing deltaX value of "wheel" event. The value 100 means 1.0. In nsEventStateManager, the deltaX value which is caused by a native event multiplies by the pref value. When two or more modifier keys are held, "default" pref is used. Currently, value between less than 100 and larger than -100 is not allowed.
; '''mousewheel.default.delta_multiplier_y'''
; '''mousewheel.with_alt.delta_multiplier_y'''
; '''mousewheel.with_shift.delta_multiplier_y'''
; '''mousewheel.with_win.delta_multiplier_y'''
: Customizing deltaY value of "wheel" event. The value 100 means 1.0. In nsEventStateManager, the deltaY value which is caused by a native event multiplies by the pref value. When two or more modifier keys are held, "default" pref is used. Currently, value between less than 100 and larger than -100 is not allowed.
; '''mousewheel.default.delta_multiplier_z'''
; '''mousewheel.with_alt.delta_multiplier_z'''
; '''mousewheel.with_shift.delta_multiplier_z'''
; '''mousewheel.with_win.delta_multiplier_z'''
: Customizing deltaZ value of "wheel" event. The value 100 means 1.0. In nsEventStateManager, the deltaZ value which is caused by a native event multiplies by the pref value. When two or more modifier keys are held, "default" pref is used. Currently, value between less than 100 and larger than -100 is not allowed. NOTE: deltaZ value never becomes non-zero if it's a trusted event. So, these prefs never work actually.
