Understanding V I Modes

• V I operates in two modes: command mode (for executing commands) and insert mode (for typing text).

• To switch to insert mode, press 'i', and to return to command mode, press 'Escape'.

Basic Commands for File Management

• To save a file, use 'Shift + ZZ' or type ':wq!' and hit 'Enter'.

• To delete text, use 'x' to remove a character or 'dd' to delete an entire line.

Editing and Navigating Text

• Use arrow keys to navigate in command mode, but not in insert mode.

• To replace text, switch to command mode and use 'r' followed by the new character.

Searching and Undoing Changes

• To search for a word, use '/' followed by the word and hit 'Enter'.

• To undo the last action, press 'u' in command mode.

Practice and Familiarization

• It's encouraged to practice using V I by creating and editing various files to become proficient with its commands.
