scan-buf-previous-region is an interactive autoloaded compiled Lisp function in `help-at-pt.el
'.
(scan-buf-previous-region &optional ARG)
Go to the start of the previous region with non-nil help-echo.
Print the help found there using `display-local-help'. Adjacent
areas with different non-nil help-echo properties are considered
different regions. With numeric argument ARG, behaves like
`scan-buf-next-region' with argument -ARG.
