Assuming that in this situation you have two frames - the main frame and the help frame: What does evaluating the form (let ((buffer (window-buffer (frame-root-window (next-frame)))) (foo (get-buffer-create "*foo*"))) (with-current-buffer foo (insert (buffer-name buffer) "\n" (with-current-buffer buffer (buffer-substring 1 (point-max)))))) in the main frame via M-: put into buffer *foo*? martin
