Represent a particular revision of a file or directory.
The box at the bottom of the version marker allows you to collapse or expand the display of subsequent versions on a particular branch.
- If the box in a particular version marker contains a plus sign (+), there are hidden subsequent versions on the branch; clicking the box expands the display to show these subsequent versions.
- If the box contains a minus sign (-), clicking it collapses the version tree to hide all subsequent versions on that branch.
