To browse the history of an item under version control:
Select the item you are interested in. The item may be in a working copy or repository browser.
Unlike the timeline view, you can only select a single item when switching to the log view.
Switch to the log view by selecting View > Log (key equivalent ⌘2) or by clicking the log button in the browser view toolbar:
See Downloading and Caching Your Repository’s History for more information.
The log view will be loaded and displayed with the item’s history.
