Each frame consists of several distinct regions. At the top of the
frame is a menu bar , which allows you to access commands via a
series of menus. On a graphical display, directly below the menu bar
is a tool bar , a row of icons that perform editing commands if
you click on them. At the very bottom of the frame is an echo
area , where informative messages are displayed and where you enter
information when Emacs asks for it.
