Thank you for reporting this.

This functionality is now restored. There is a slight difference from
the original behaviour.

Invoking ChangeMode() without parameters will toggle a text's mode from
current mode to previous mode (and back again). When a text is created
its previous mode is set to BaseMode. So, initially, cs-ESC will toggle
between current mode and BaseMode.

If however the text's mode is changed from, say, X to Y then cs-ESC will
toggle between modes X and Y. You can no longer change the mode back to
BaseMode using cs-ESC. This is different from earlier behaviour where
cs-ESC would always toggle current mode <-> BaseMode, even after a mode

To allow you to still change back to BaseMode two new keybindings have
been created (in 4.68a1); c-M and cs-M. c-M works the same as cs-ESC.

cs-M always toggles between the current mode and BaseMode. This means
that if you've changed from mode X to Y and then press cs-M you can not
change back to mode X using c-M (or cs-ESC) as this will toggle between
BaseMode and Y now (as BaseMode is current mode and Y is previous mode).
