** 'M-TAB' now invokes 'completion-at-point' also in Text mode.
|

By default, Text mode no longer binds 'M-TAB' to 'ispell-complete-word'.
|

Instead, this mode arranges for 'completion-at-point', globally bound to
|
||||
'M-TAB', to perform word completion as well. You can have Text mode

bind 'M-TAB' to 'ispell-complete-word' as it did in previous Emacs

If your terminal cannot display 'У', or if you want to get the old

behavior back for any other reason, you can do that using the
