In the Browser Workbench, you can restore the previous version of
the selected segments with the option in the workbench toolbar or by clicking the
restore icon that appears to the right of the segments with history
(that is, with more than one version). The difference between these
two ways of restoring the previous version is that the first allows
you to select multiple segments to restore, while the second acts
only upon the segment the icon is beside.
Note: This Restore Last Version icon to the right of the target segment displays only if Show Segment Details is enabled in the toolbar.
Here is a segment that has previous versions:

Clicking the restore last version button (circled) pastes the previous entry back to the segment:
