        !            18: uses three  modes: visual command  mode, colon command  mode, and

        !            24: Visual-command mode closely resembles text-input mode.  One quick
        !            25: way to tell the modes apart  is to press the <esc> key.  If elvis
        !            26: beeps, then you are in visual-command mode.  If it does not beep,

        !            29: 
        !            30: Most visual-mode  commands are one keystroke  long.  The commands
        !            31: are  in two  groups: movement  commands  and edit  commands.  The
        !            32: former group moves the  cursor through the file being edited, and
        !            33: the latter group alters text.
