At the bottom of the screen, you will see a line containing some numbers and letters. It is named the status bar , because it reports to you part of the internal state of the editor.
Alphabetic characters insert text, cursor keys move the cursor, and so on.
If not, complain with your system administrator. The small letters represent instead user flags that you can turn on and off. For a thorough explanation of the meaning of the flags on the status line, see The Status Bar . Immediately, the menu bar will appear, and the first menu will be drawn. You can now move around menus and menu items by pressing the cursor keys.
