Using a hosted Mercurial repository (e.g., Bitbucket)

To put an existing Zim wiki under version control (using Mercurial hosted on Bitbucket), I:
1. Created the repository on Bitbucket.
2. Created and initialized a local directory, and committed and pushed a file to verify that the directory was properly under version control.
3. Copied into that directory the entire directory tree and files from an existing Zim wiki.
4. Committed and pushed all the files to Bitbucket from the command line (successfully).
5. Enabled the version control plugin in Zim.
6. Opened up the version-controlled copy of the wiki.
7. Edited a page and used the File/Save version command.

The revision was not pushed to the Mercurial repository on Bitbucket. What needs to be done differently?

[Edit] After running "hg push" at the command line in the repository is updated. The "File/Save version" apparently does not issue the "push" command. Should it?

Thanks.
