This is driving me mad. Back from the holydays, Unity doesn't "see" my "W" key anymore. My vertical axe now just goes down. If I remap the key in input with something else, everything works. The key works while typing in the editor (changing objects name), but strangely in scene view instead of going to move mode (Q, E and R works) it toggles pivot move from center to pivot. This is soo strange....
Check out Edit >> Preferences >> Keys tab Make sure W is still set for Tools/Move
