It doesn't yet. I should enter an issue for this. Someone else at some point asked for a pull request for keyboard shortcuts (and other stuff), but at the time I thought that the extension wasn't stable enough feature-wise, and I didn't want to deal with anything which would need constant revision before the feature set stabilize. For instance, I eventually trashed the context menu code that was put in too early because of this. But now that it definitely is approaching v1.0, it probably does make sense to address that issue.
