Post revisions (including any autosaves) are accessible in the Publish box to the right of the post edit screen. If a post has revisions, you'll be able to click a Browse link to view them (see Figure 5).
Figure 5 The Publish box has a link to let you browse revisions.
When you have an autosave, it's listed at the top of the Revisions screen in red, as shown in Figure 6.
Figure 6 An autosave is listed at the top of the Revisions screen.
The current version of your post displays below the autosave. You can compare any two revisions by ticking the Compare Any Two Revisions checkbox (see Figure 7). To find the revisions you want to compare, either click the Previous or Next buttons or use the blue arrow sliders to navigate through available revisions.
Figure 7 Drag the sliders or use the Previous/Next buttons to see what has changed between revisions.
Once you've selected the two revisions you want to compare, you'll see any content changes side by side. At the top of the screen, the post author's name and icon appear, as well as the date and time of the revision. You can select the revision you want to restore by clicking it and then clicking the Restore This Revision button (see Figure 8). You can also return to the post edit screen without changing to a previous revision; just click the post title at the top of the Revisions screen.
Figure 8 Differences between revisions are highlighted.
