Yes, "win rc" embeds a rc shell window in Acme, I can undo in the shell window, that's perfect!
But the edit in tag line can't be undo, I find the Undo command has no effect if it's on the top main tag line or the column tag line, it only works on window tag line and only undo editing in the text window. I tried p9p Acme on Mac OS X, seems the mouse button emulation with trackpad is broken, p9p Acme doesn't response to Shift + Secondary Click, this is probably my problem, won't play it now until I'm more familiar with 9front in Virtualbox.
