find-outline-item

Arguments: outline &optional item-value &key (key (function identity)) test only-after-index

Finds and returns the first currently visible outline-item on outline whose value is item-value. If no such outline-item is found, then nil is returned.

key and test are used as in find and related functions for finding the matching value. The value of key should be a function (suitable as the first argument to funcall) of one argument that is applied to a candidate value before comparing it with item-value. The comparison is done with the value of test, which should be a function (suitable as the first argument to funcall) that accepts two arguments and returns true if the arguments should be considered identical. test defaults to the value of the on-change-test event property of outline-item.

If only-after-index is true, it should be a non-negative integer indicating the position of some outline-item to make the search begin with the item just following it (and proceeding downward as usual).
