+- **Mouse Usage**: `set mouse+=a` turns mouse usage on in all vim modes (normal, visual, insert, and command-line). This allows you to use the mouse for various actions like selecting text, resizing windows, and scrolling.
 - **Line Numbers:** `set number` displays absolute line numbers, while `set relativenumber` makes navigation easier by showing relative numbers.
 - **Cursor Highlighting:** `set cursorline` makes it easy to see where your cursor is.
 - **Indentation Control:** `tabstop`, `shiftwidth`, and `expandtab` ensure consistent spacing and indentation.
 - **Autoindent:** Helps maintain indentation consistency when writing code.
 - **Text Wrapping:** `set nowrap` prevents long lines from wrapping, keeping code readable.

 In Vim, the **leader key** is a customizable key that serves as a prefix for user-defined shortcuts, making commands faster and more intuitive. By default, the leader key is set to `\` (backslash), but it can be changed to another key, such as the **comma** or **space**, to improve usability.
 
 ### **Why Use the Leader Key?**
+
 - **Simplifies Commands:** Instead of typing long Vim commands, you can assign shortcuts to them.
 - **Improves Speed:** Reduces keystrokes for common actions.
 - **Personalized Workflow:** Tailor Vim to your habits and needs.
 
 ### **Setting a Custom Leader Key**
+
 You can redefine the leader key in your `.vimrc` file:
+
 ```vim
 let mapleader=","  " Set leader key to comma
 ```
 
 ### **Using the Leader Key**
+
 Once defined, the leader key can be used to create custom shortcuts:
+
 ```vim
 nnoremap <leader>w :w<CR>    " Save file with ,w
 nnoremap <leader>q :q<CR>    " Quit Vim with ,q
 nnoremap <leader>x :x<CR>    " Save and exit with ,x
 ```
+
 This means pressing **`,` followed by `w`** will save the file instead of typing `:w<CR>` manually.
