Lately im struggling to find how we can access emacs menu bar. Its visible on top of screen but i cant do anything on it. The menu bar can not be clicked by mouse (im installing no x emacs anyway and open it on mate terminal). Alt key will access mate terminal menu bar … hmm so i cant use alt key. Later i tried Esc key and its work. Press Esc then release, then press ` (backtick, key below Esc) and voila prompt will show on the bottom screen. We can browse using arrow key or page up to go to page containing menu link above the prompt. Press enter to execute selected menu or link. Its better not to memorize Emacs key binding and use menu, isnt it ?
