viper-unrecord-kbd-macro
viper-unrecord-kbd-macro is a compiled Lisp function in `viper-macs.el
'.
(viper-unrecord-kbd-macro MACRO-NAME STATE)
Delete macro MACRO-NAME from Viper STATE.
MACRO-NAME must be a vector of viper-style keys. This command is used
by Viper internally, but you can also use it in `viper-custom-file-name'
to delete pre-defined macros supplied with Viper. The best way to avoid
mistakes in macro names to be passed to this function is to use
`viper-describe-kbd-macros' and copy the name from there.
