Emacs tips: Searching and replacing
Even if you use Emacs every day, sometimes you'll misplace a word or phrase. When that happens, you'll be glad that Emacs has flexible, built-in search and replace commands to help you find exactly what you are looking for.
You start a basic search in Emacs by typing Ctrl-s. This launches isearch-forward, an incremental search. As soon as you type Ctrl-s, you can begin typing the search string that you are looking for, and Emacs will search for it as you type, highlighting the first match.
Emacs might find the first match after just the first few characters -- saving you keystrokes and freeing you from worry if you are looking for some complex, easily misspelled string. If you do mistype a character, just hit Backspace and re-type the correct one -- Emacs will keep up with you as you make changes.
As soon as you have found the word you are looking for, all you have to do is click in the active window to get back to your text editing; the search ends automatically.
