 * **bookmark:** the current bookmark (requires the [bookmarks]() extension)
 * **branch:** the current branch
+* **rev:** the repository-local changeset number of the current parent.  This does not take into account merges (which have two parents) -- see the `rev|merge` keyword for that.
+* **rev|merge:** the repository-local changeset number of the changeset you're merging with if you're currently merging, otherwise nothing
 * **root:** the full path to the root of the current repository, without a trailing slash
 * **root|basename:** the directory name of the root of the current repository.  For example, if the repository is in `/home/u/myrepo` then this keyword would expand to `myrepo`.
 * **status:**  `!` if the repository has any changed/added/removed files, otherwise `?` if it has any untracked (but not ignored) files, otherwise nothing.
