register--read-with-preview-function is a variable defined in
register.el.gz.
Value
register-read-with-preview-traditional
Documentation
Function to use for reading a register name with preview.
Should implement the behavior documented for register-read-with-preview.
Two functions are provided, one that provides navigation and highlighting
of the selected register, filtering of register according to command in
use, defaults register to use when setting a new register, confirmation
and notification when you are about to overwrite a register, and generic
functions to configure how each existing command behaves. Use the
function register-read-with-preview-fancy for this. The other
provided function, register-read-with-preview-traditional, behaves
the same as in Emacs 29 and before: no filtering, no navigation,
and no defaults.
