Merging Blocks
Difference blocks are highlighted within each revision and may be insertions, deletions, or changes. You can select the blocks you want to merge by this method.
The merging by blocks functions are accessible from the Edit menu and the shortcut menu. The following outlines the operations you can use:
Merge Block replaces a block in the Merge Result. The block you select to merge is inserted, replacing the corresponding block in the Merge Result.
Merge Block Above inserts the selected block above the adjacent block in the merge result file.
Merge Block Below inserts the selected block below the adjacent block in the merge result file.
You can also perform these operations in the following ways:
Double-click a block in the Merge From or Merge To panes to replace the adjacent block in the Merge Result.
Drag blocks from the Merge From and Merge To panes to the Merge Result pane.
You must save the merge result file to complete the merging operation. For information on saving merge results, see “Saving Merge Results”.
