C-z, C-t, and C-o are already taken, and are very old bindings.  C-t
in particular is very useful and frequently-used (by me, FWIW), and
also matches the default binding in Bash, GDB CLI, and elsewhere.  A
recent discussion demonstrated that at least for C-z enough people are
against changing its binding, even though we have "C-x C-z" to do the
same.

These data points suggest that usurping these keys may not be easy, to
say the least.
