Normal, Insert and Visual Mode
Vim has three different modes. 1) Normal mode, 2) Insert mode, 3) Visual mode.

Normal mode is sometimes called Command mode, especially after pressing :. When you press the : key on your keyboard, the : letter shows in the bottom left corner of the screen. You can run some commands e.g., replace words, save file, exit Vim. By pressing the esc key, you can stop Command mode.
Insert mode
