Changes allows you to compare, merge and edit text files which you choose in the Session Chooser or while Comparing Directories.


The files will be laid out in a side-by-side fashion with differences highlighted in red (depending on your preferences of course) while matching areas will be colored normally. You can edit, merge blocks of the file, and save your changes.


Navigation


To quickly navigate between changed areas of the file, use the Previous Diff and Next Diff toobar buttons, or the Previous Difference and Next Difference menu items of the Merge menu.


Merging Text Blocks


Use the Merge From Left and Merge From Right toolbar buttons or the Left to Right or Right to Left items of the Merge menu.


Saving and Reverting Edits


To save your changes to either file, select the Save item from the File menu. 


If you want to save just the Original file, select the Save Original As… menu item. If you want to save just the Modified file, select the Save Modified As… menu item. 


If you decide you don't want to save your changes, select the Revert item from the File menu.
