Left shift doesn't work in KSP or other Unity games
I've got an issue in several different unity games: the LeftShift key doesn't recognize, nor does RightShift. Every other key works fine, and LeftShift works in other games and outside of Kerbal.
I'm running Windows 8.1.
Any ideas?
Synergy was hijacking the shift key. Quitting Synergy solved the issue.
