I was using
Go to Git Workspace -> Click Show History(Right Click Project) -> RIght-Click on the commit I want to revert and press Revert Commit.
VCS -> Show Changes View
VCS -> git
git revert <sha>
If you go to Changelist -> Log, and there select the commit, you've got a change detail in the right panel. There you can select all and click a button (or right click -> revert selected changes).
