How to rollback everything to previous commit

Question

Recently in a project with multiple people, a commit was made as seen in the image below. Marked in red you can see a commit with the description/comment of \'Merge?\'.

Answer 1

If you have pushed the commits upstream...

Select the commit you would like to roll back to and reverse the changes by clicking Reverse File, Reverse Hunk or Reverse Selected Lines. Do this for all the commits after the commit you would like to roll back to also.

If you have not pushed the commits upstream...

Right click on the commit and click on Reset current branch to this commit.
