D.4 Problems with vi Commands

  • When you type commands, text jumps around on the screen and nothing works the way it's supposed to.

    Make sure you're not typing the J command when you mean j .

    You may have hit the [CAPS LOCK] key without noticing it. vi is case-sensitive. That is, uppercase commands (I , A , J , etc.) are different from lowercase commands (i , a , j ), so all your commands are being interpreted not as lowercase but as uppercase commands. Press the [CAPS LOCK] key again to return to lowercase, press [ESC] to ensure that you are in command mode, then type either U to restore the last line changed or u to undo the last command. You'll probably also have to do some additional editing to fully restore the garbled part of your file.
