POST https://api.example.com/users
Content-Type: application/json

{
  "name": "John"
}
```

Use `<leader>kr` to run request under cursor.

## Tips & Tricks

### Learn Vim Motions
Enable Hardtime (`<leader>ht`) and Precognition (`<leader>vp`) to improve your vim skills.

### Quick File Switching
Use Harpoon to mark important files (`<leader>ha`), then jump instantly with `<leader>1-5`.

### Multi-Cursor Editing
Like VS Code: `<C-d>` to select word, keep pressing for more occurrences.

### Smart Increment
`<C-a>` on `true` → `false`, on `GET` → `POST`, on dates, colors, etc.

### Split/Join Code
`<leader>tj` on arrays, objects, function arguments to toggle between single/multi-line.

## Troubleshooting

```vim
:checkhealth          " Run health checks
:Lazy sync            " Sync plugins
:Mason                " Check LSP servers
:LspInfo              " Check LSP status
```
