YouTube Excerpt: Vim has three primary modes that you should be familiar with: Normal mode, Insert mode, and Command-line mode. Each mode has its specific function and purpose. Let's go over each mode in detail and how to switch between them. 1. Normal Mode (Default Mode) When you open a file in Vim, you start in Normal mode (sometimes referred to as "Command mode"). In this mode, you can move around the file, delete text, copy/paste, and execute various commands. Common Actions in Normal Mode: Navigation: Move around the file. Arrow keys or h, j, k, l (left, down, up, right). gg to go to the start of the file. G to go to the end of the file. 0 to go to the beginning of a line. $ to go to the end of a line. Deleting: d followed by a motion deletes the content. Example: dw deletes a word. dd deletes the entire line. x deletes a single character under the cursor. Copying (Yank) and Pasting: yy to copy (yank) a line. p to paste below the cursor. P to paste above the cursor. Searching: /search_term to search for text. n to go to the next occurrence. N to go to the previous occurrence. Undo/Redo: u to undo. Ctrl+r to redo. Saving and Quitting: :w to save. :q to quit. :wq to save and quit. :q! to quit without saving. Switching to Normal Mode: Press Esc to make sure you are in Normal mode, regardless of what mode you’re currently in. 2. Insert Mode (For Typing Text) Insert mode is where you can type and edit text. You can enter Insert mode from Normal mode and return to Normal mode when you're done typing. Entering Insert Mode: Press i to insert text before the cursor. Press I to insert text at the beginning of the line. Press a to insert text after the cursor. Press A to insert text at the end of the line. Press o to open a new line below the current line and enter Insert mode. Press O to open a new line above the current line and enter Insert mode. Exiting Insert Mode: Press Esc to return to Normal mode. 3. Command-line Mode (For Executing Commands) Command-line mode is where you can execute Vim commands such as saving, quitting, searching, and more. To enter Command-line mode, you must first be in Normal mode. Entering Command-line Mode: Press : to enter Command-line mode at the bottom of the screen. Once in Command-line mode, you can type various commands like :w to save, :q to quit, and many more. Common Commands in Command-line Mode: :w to save the file. :q to quit Vim. :wq to save and quit. :q! to quit without saving changes. :e filename to open a new file. :x to save and quit (same as :wq). :s/old/new/ to replace the first occurrence of "old" with "new" in the current line. :s/old/new/g to replace all occurrences in the current line. :set number to show line numbers. Exiting Command-line Mode: Press Enter to execute the command. Press Esc to exit Command-line mode without executing a command.
