Is it possible to evaluate entire buffer in Emacs?

Question

Hello.

In order to evaluate elist in Emacs i need to position cursor on the last parenthesis and emit C-x e. But is it possible to evaluate a text in entire buffer as a single elisp program without a need to position cursor etc?

Answer 1

 M-x eval-buffer

or [alt]+'x' and then type 'eval-buffer' or just type part of it and tab to autocomplete.
