Most people know c-r starts an incremental reverse search, but I wonder how many people know that c-r <return> switches from incremental search to prompting for the search string in the minibuffer, so you can yank in something copied externally (e.g. a link from a browser), possibly edit it a bit in the minibuffer, then c-r to actually search for it. #emacs #tidbit (Works for c-s too.)
