accept-line (Newline or Return)
add_history(). If this line is a modified history line, the history line is restored to its original state.
yank-last-arg (M-. or M-_)
yank-nth-arg. Successive calls to
yank-last-argmove back through the history list, inserting the last word (or the word specified by the argument to the first call) of each line in turn. Any numeric argument supplied to these successive calls determines the direction to move through the history. A negative argument switches the direction through the history (back or forward). The history expansion facilities are used to extract the last argument, as if the ‘!$’ history expansion had been specified.
