must retrieve the file into the computer’s memory. The l software displays the document on the screen. You then make entries by moving the cursor to the places in the document   where   you   want   to   make   changes.   Two l modes of operation are used—typeover and insert. As the words imply, if you are in typeover mode, you will replace  what  is  presently  there.  If  you  are  in  insert mode, the material to the right of the cursor will move to the right as you enter new material. These, along with other  features,  are  shown  in  figure  3-2.  Take  a  few l minutes to study the figure. The basic features you will use are as follows: l l l Cursor movement keys— Move the cursor up, down, right, left, to top/bottom of document, to next/previous   page/screen;   search   to   find   a character   string   or   function   code   in   the document. l Insert mode—  To  add  letters/characters,  words, sentences, and so on. l Figure 3-2.—Examples of basic features found in word processing  packages. Delete key— To take out unwanted characters, words, sentences, and so on. Backspace  key—  To erase words to the left of the  cursor  one  character  at  a  time.  (NOTE:  In some   packages   this   key   may   be   defined differently. For   example,   it   may   backspace without deleting.) Typeover mode— To replace text by typing over it. Wordwrap—   As   you   enter   text,   words automatically  move  to  the  next  line  when  the right margin is reached. You do not have to press the return key at the end of each line as you do on a  typewriter. Cut and paste function— Allows you to move material  from  one  place  in  a  document  to another. Function   keys—  To  underline,  center,  tab, indent;   put   text   in   bold;   use   subscripts/ superscripts. You can put text in columns; add headers, footers, footnotes, page numbers, date, and so on. Special Features Many   word   processing   programs   include dictionaries   and a  thesaurus.   These  enable  you  to check  for  correct  spelling  and  to  look  for  synonyms. Some of the dictionary routines even provide a list of correctly spelled words you might have meant. In this case, you can correct a mispelled (or is it misspelled) word by selecting the correctly spelled word from the list  on  the  display  screen.  The  same  is  true  of  the thesaurus, the software lists synonyms on the screen. You select the one you want, and it replaces the original word with the selected synonym. Some  word  processing  programs  have  automatic paragraph  numbering  and outlining  features.  Once you  have  created  the  outline  or  document,  you  can delete   or   add   entries,   and   the   software   will automatically   renumber/reletter   the   outline   or paragraphs in the document. Some  word  processing  programs  have  indexing capabilities.   You   can   tell   the   software   which words/terms   are   to   be   included   in   an   index.   The software  will  then  automatically  create  the  index  in alphabetical order, with the appropriate page numbers. 3-8
