my mouse has 5 buttons but i only utilize 3 (other two buttons in odd positions).
-left click :1
-right click: 2
-wheel click: 3
keyboard: i will only mention the ones iv changed.
-E: zoom
-left shift: change target
-left crtl: jump
-R: alpha strike
-space bar: 4
lets be honest, unless most of the mechs you pilot can jump, space bar is useless in the default setting. reason why i dont use number keys is because those keys require me to use my 3 primary movement fingers. (fore.,middle, ring)
