* doc/emacs/basic.texi (Basic Undo): Explain the C-/ situation in xterm
AFAICT, in ttys you can send a `C-_` to Emacs either by pressing
`C-/` (e.g. xterm, uxterm, rxvt, xfce4-terminal, gnome-terminal)
or by pressing `C--` (e.g. rxvt, Linux console).

On a terminal that supports the @key{Control} modifier on all other
keys, the easiest way to invoke @code{undo} is with @kbd{C-/}, since
that doesn't need the @key{Shift} modifier. On terminals which allow
-only the ASCII control characters, @kbd{C-/} does not exist, but many
-of them allow you to omit the @key{Shift} modifier when you type
-@kbd{C-_} (in effect pressing @kbd{C--}), making that the most

Although each editing command usually makes a separate entry in the
undo records, very simple commands may be grouped together.
