When trying to create multi keybind combinations ie. Right CTRL + Mouse Wheel Up for any action (lets say for reports sake Zero Up) the keybind gets reverted to Right CTRL, Mouse Wheel Up after applying changes and reloading keybindings screen.
This renders possibility to use more flexible and advance key combinations impossible as instead of triggering Zero Up by pressing Right Control
+ Mouse Wheel Up you trigger what ever action is bound to those keys.
