This buttons works fime to zoom from infantry.
But this buttons is not working in SOS, TWS NFOV\WFOV(not affect to mag. switch), from cockpits(works like Zoom in\Zoom out).
The main problem is - if i sacrifice "mouse wheel" for zoom issues, i still away from good solution. For infantry/cockpits i need toggled/stepped zoom unchained from mouse button. For gunner i need fast optic zoom(not NUM_buttons). For weapons optic - working zoom modes. And "zoom toggle" works in ~30% of zoom situations.
