That's ridiculous! The only invisible things in Emacs deserve to be so. For everything else, there is a menu bar which is also visible in terminal `emacs -nw` mode. Just add `(xterm-mouse-mode t)` to ~/.emacs to make sure the mouse works properly. Very pointy, very clicky, and nice pretty menus that tell you the shortcut of each function.
