I found already a topic which is indirectly touching the subject, but just wanted to rise the flag to developers and users: Mechwarrior Online is the only game I was able to find so far, which is ignoring keystroke assignments for additional mouse buttons in Logitech SetPoint.
You see, mouse from Logitech MX5500 revolution set has at least 8 additional "buttons" which are very convenient to use in "non-trivial" games . Of course by default they are not supported, but you can assign them regular keyboard combinations. For example make "quick search" button produce keyboard "F" button signal, or "Ctrl+G" , or "F1". But they just don't work in MWO.
And that's sad.
