When comparing or merging HTML contributors, Diff Merge renders in the browser pane the HTML code in the currently selected contributor or merge results pane. This pane appears adjacent to the merge results pane. If you are not comparing or merging HTML files, this pane does not appear.
When the merge results pane has focus, each time you resolve a difference or undo a difference resolution, the browser pane shows the up-to-date rendering.
The browser pane contains the standard Microsoft Internet Explorer, which has its own shortcut menu. This is the shortcut menu that Internet Explorer provides when you hold the cursor on non-image portions of an HTML page.
