I'm completely new to source control and Subversive, and I've committed changes to a file that shouldn't have been modified. I've done over an hour of searching documentation and the Internet about this, but I guess I'm not familiar enough with the terminology. Also, a lot of source control resources seem to be for command line users.
Here's what I've tried so far: first, I used the Team > Revert option, but I've since found that that only affect the local copy. I looked at the repository's web interface, but it only provided a diff tool, not a rollback tool. I've also opened the History tab and found "Revert Changes from Revision X" and "Switch to Revision X" in context menus.
Based on the docs I've found, I think one of those is what I need, but I'm not sure which. Also, I don't know whether to select the current revision, because that's the one I want to undo, or the one before it, because that's the one I want to get to. If this were a code problem, I'd just run a little test, but in this case I'm afraid I'll make things worse by selecting the wrong option and I don't want to clutter the repository with a useless test file.
So, in summary: How can I use Subversive to roll back a single file to its immediately previous version?
