This tutorial assumes full knowledge +of tutorial #1, and familiarity with tutorial #2. Lines which begin +with >>> mark exercises you should try. When you want to exit this +tutorial type 'Z''Z' . + + +SIMPLE INSERTION +---------------- +You spend most of your time in vi inserting text. As you might expect, +there are several commands to begin insertion. + + 'o' OPEN a line below the cursor + 'O' OPEN a line above the cursor + + 'i' INSERT starting before the cursor + 'I' INSERT at the beginning of the line + + 'a' APPEND starting after the cursor + 'A' APPEND at the end of the line + +Remember to type ESC to leave insert mode. If you don't have an ESC key +type C-[ (control [ ). + + ESC ESCAPE from insert mode + +>>> Move the cursor to this line. Type 'O' , enter your name. Press ESC. +>>> Next type 'o' , enter the date. Press ESC. + +Note that 'O' opens the line above and puts you in insert mode, +while 'o' opens the line below and also puts you in insert mode. + +>>> Type 'a' on any line above, enter your name. Press ESC. Do the +>>> same for 'A'. + +>>> Read the following. Your goal is to take the sentence fragment below: + + BROWN FOX OVER THE SEVEN LAZY + +>>> and convert it to + + THE QUICK BROWN FOX JUMPED OVER THE SEVEN LAZY DOGS. + +>>> To do this type: +>>> 'I' to insert THE QUICK (then press ESC) +>>> move the cursor to after the X in FOX +>>> 'a' to insert JUMPED (then press ESC) +>>> 'A' to insert DOGS. (then press ESC) +>>> Now move to the sentence fragment and make the changes outlined above. + + +JOINING LINES +------------- +Often it is convenient to join two short lines into one line. There +are several ways to do this. The easiest is the J command. Other +methods will be explored in tutorial #5. + + 'J' JOIN two lines + +>>> Go to the first line in the block below. Type J. Type J again. + + Example: NOW IS THE TIME + the walrus said + TO THINK OF MANY THINGS + +In the event that joining lines creates a line which exceeds the width +of the screen, you can break the line by typing i and pressing RETURN. + + +SUBSTITUTING TEXT +----------------- +Substituting combines the delete command and the insert command into a +single step. + + #'s' SUBSTITUTE for # characters + #'S' SUBSTITUTE for # whole lines + + +In order to substitute text you have to know how much text you want to +delete. Consider the following examples: + + '3''s' SUBSTITUTE the next 3 characters for what will be typed + '7''s' SUBSTITUTE the next 7 characters for what will be typed + +>>> Change the SAMPLE DEFINITION below. To do this: +>>> move the cursor to the T in TWO +>>> type '3's +>>> type FOUR then press ESC + + SAMPLE DEFINITION: A string quartet is defined to be + a group of TWO musicians. + + +REPLACING TEXT +-------------- +The 'r' and 'R' commands allow you to directly type over existing text. + + 'r' REPLACE character (NO need to press ESC) + 'R' enter over-type mode + +>>> Correct each of the TYPOs on the sample line below. To do this: +>>> move the cursor to the misspelled character +>>> type 'r' +>>> type the correct character + + SAMPLE: maintanence conveniance complience applience dilagent + +>>> Use the over-type command, 'R' , on the sample line above. +>>> Type 'R' then type the name of a local restaurant. Press ESC. + + +CHANGING TEXT +------------- +The change command combines insertion, deletion, and the movement +commands. (Recall that the movement commands were taught in tutorial +#2.) Change is probably more useful than replace or substitute. The +general form of the change command is: + + 'c'movement CHANGE to where the movement command specifies + +Consider the following examples: + + 'c''w' CHANGE to the beginning of the next WORD + 'c''$' CHANGE to the end of the line + 'c'')' CHANGE to the beginning of the next sentence + 'c''t'e CHANGE 'TIL the next e + 'c''3''w' CHANGE the next 3 WORDS + 'c''c' CHANGE a line (cc is a special case of the c command) + 'c''}' CHANGE to the end of the paragraph + +>>> Follow these steps: +>>> 1. move to the desired location in the practice paragraph below +>>> 2. type 'c''w' (change to the beginning of the next WORD) +>>> 3. type your name +>>> 4. press ESC + + PRACTICE here. Now is the time for all good users to learn the + editor. The quick red fox jumped over the seven lazy fish. Now + is the time for all good users to learn the editor. The quick + brown computer jumped over the seven lazy users. END PRACTICE + +>>> Experiment by using a variety of options for step #2. Try +>>> out 'c''$' 'c'')' 'c''t'e 'c''3''w' 'c''c' 'c''}' on the practice paragraph above. + +Note that the change command follows the same pattern as the delete +and yank commands which were explored in tutorial #3. + + +SUMMARY +------- + + 'o' OPEN a line below the cursor + 'O' OPEN a line above the cursor + + 'i' INSERT starting before the cursor + 'I' INSERT at the beginning of the line + + 'a' APPEND starting after the cursor + 'A' APPEND at the end of the line + + ESC ESCAPE from insert mode + + 'J' JOIN two lines + + #'s' SUBSTITUTE for # characters + #'S' SUBSTITUTE for # whole lines + + 'r' REPLACE character (NO need to press ESC) + 'R' enter over-type mode + + 'c'movement CHANGE to where the movement commands specifies + (e.g. 'c''3''w' 'c''$' 'c''c' ) + + +These commands should improve your ability to insert text efficiently. +The next tutorials deal with advanced commands and tricks which can +further speed up your editing. + +Copyright (c) 1992 Jill Kliger and Wesley Craig.
