Tips on Using VI Editor (continued)
Changing multiple characters to uppercase
In visual mode, with the characters to change selected, press U (uppercase) to change them to uppercase. Press u (lowercase) to change them to lowercase.
In command mode, the same effect can be achieved on a single character by placing the cursor on the letter and press the tilde sign (~).
Jumping from line to line
You can jump from line to line by marking them first. To mark a line, press the key ’m’ followed by a letter e.g. ma
This will mark the line your cursor is at in the buffer ‘a’.
Then when you are at any other position in the file, press the aprostrophe key (‘) followed by the same letter e.g. ‘a
This will bring the cursor (and the screen) to the line that you marked.
