How might one compare two org trees?

I copied an org tree. Oops. I'm not sure if I made changes to one of them. What are one (or more) ways I might compare them? I suppose I could do this: 1. find a new buffer/file 2. copy and yank one tree to the new buffer, save it 3. copy and yank the other tree to the new buffer 4. do a `M-x ediff-current-file` or `diff-buffer-with-file`. 5. resolve differences in the main org file 6. kill the new buffer and delete the corresponding work file I was just wondering if there were some more direct methods.

What you want to do is diff two regions. If there isn't already a function for that, you could write one that does the steps you described, using the contents of two regions.

Thanks. I actually found a potential answer to this on stackoverflow. I haven't tried it out though, ymmv. From https://stackoverflow.com/a/18106677: ___ BTW, if you want to see the differences between two blocks of text in the same buffer, you can do it as follows: - make sure smerge-mode is loaded (e.g. `M-x load-library RET smerge-mode RET`). - go to the beginning of the first bloc, `C-SPC` - go the beginning of the second bloc, `C-SPC` - go to the end of the second bloc, `M-x smerge-makeup-conflict RET` - then you can use `C-c ^ R` or `C-c ^ =` to view the differences. Note that this works better if the two blocs are pretty much consecutive. ___

You could also use `ediff` for side-by-side diffs. - Compare arbitrary regions - `ediff-regions-wordwise` - `ediff-regions-linewise` Use `org-mark-subtree` to create regions. - Compare buffers - `ediff-buffers` Use `C-u M-x org-tree-to-indirect-buffer` to create two buffers narrowed to trees. These approaches don't require blocks of text to be consecutive.

Great, thanks!!!
