Thanks to some great feedback from Gil, I've added some hotkeys. I also made a new release (version 1.8, for those following along in CVS), which includes the hotkeys, as well as the Python 3 compatibility.
On December 3rd, Python 3.0 was released. Python 3.0 is not backwards-compatible with Python 2.x. I made some changes to TkRow so that it would work with either 2.x or 3.0. I did not make a new release, but you can find tkrow.py version 1.4 in the CVS repository.
