Obvious joke is obvious, but he could have called it the Unno Fish Shell?
Looks interesting. I expect my fingers will be even more confused than ever switching machines now (they've never learned that Alt-3 isn't # on linux or that middle-click isn't paste in Putty)
That one always bites me at other people's desks; I'd figure out how to reconfigure it if it was mine. But there's always something jarring like that when you switch between similar-but-not-quite-the-same environments.
i've gotten to the point where i can subconciously key off the window chrome to know how to paste. (half my coworkers use xterm, the other half putty.)
