Keybinding obfuscate UI info

Binding a mouse button to "firing mode" covers the UI showing the selected firing mode with "mouse x". This makes it hard to check current firing mode quickly. Having select firing mode bound to the thumb button on the mouse is nice for quick shifts, just like on a real weapon.

I suggest calling "mouse x" button "M3" or something instead, or to separate keybinding and UI info vertically. Another option would be placing the keybind after the UI info as to not bleeding into the necessary info. Doesn't really matter as long as the issue is fixed.
