@ -1651,9 +1651,10 @@ A jump table for the options with a short description can be found at |Q_op|.
The default is CTRL-F when 'compatible' is off.
Only non-printable keys are allowed.
The key can be specified as a single character, but it is difficult to
type. The preferred way is to use the <> notation. Examples: >
:exe "set cedit=\<C-Y>"
:exe "set cedit=\<Esc>"
type. The preferred way is to use |key-notation| (e.g. <Up>, <C-F>) or
a letter preceded with a caret (e.g. `^F` is CTRL-F). Examples: >
:set cedit=^Y
:set cedit=<Esc>
< |Nvi| also has this option, but it only uses the first character.
See |cmdwin|.
NOTE: This option is set to the Vim default value when 'compatible'
