MY thanks to Ms Stob
I'd like to thank Ms Stob for making me realize that I've been avoiding drag and drop for three decades. Didn't like it in 1988 and don't like it now. I have no idea why.
And I'd also like to thank her for letting me know that I'm not the only one who finds git to be baffling. Not that I think get is bad or evil. I just don't grok it. Fortuitously RCS is sufficient for my needs.
