viper: Unimplemented Features
1.6 Unimplemented Features
==========================
Unimplemented features include:
• ‘:ab’ and ‘:una’ are not implemented, since ‘:ab’ is considered
obsolete, since Emacs has much more powerful facilities for
defining abbreviations.
• ‘:set option?’ is not implemented. The current ‘:set’ can also be
used to set Emacs variables.
• ‘:se list’ requires modification of the display code for Emacs, so
it is not implemented. A useful alternative is ‘cat -t -e file’.
Unfortunately, it cannot be used directly inside Emacs, since Emacs
will obdurately change ‘^I’ back to normal tabs.
