Vim, short for Vi IMproved, is a powerful and highly customizable text editor that has been a favorite among developers, sysadmins, and power users for decades.

  • Insert Mode: Used for inserting and editing text.
  • Visual Mode: Used for selecting and manipulating blocks of text.

Understanding these modes and how to switch between them is fundamental to using Vim efficiently.
