Phooey. tcsh doesn't seem to have an equivalent. Gotta switch to zsh one day, as I hear it has a tcsh compat mode for lowered transition pain...

But I did find this new one in tcsh:

M^Z (ALT-CTL-Z) to instantly switch back to the last editor you ^Z'd. So you can bounce back and forth between editor/shell with a changed-by-one keypress combo. Cool.
