Select a file in the navigator area.
The file opens in the editor area.

Optionally, choose other revisions to compare from the jump bars below the editor area.
Choose a different revision from the jump bar under the right and the left panes. In the jump bar menu, there’s a menu item for each revision of the file. The revisions appear in chronologically order from the current local revision to the oldest committed revision.
In the comparison editor, click a change in the gutter between the two revisions, then choose Discard Change.
