| Key | Description | Command |
| ----- | ------------- | ------- |
| `w`, `Ctrl-w` | Switch to next window | `rotate_view` |
| `v`, `Ctrl-v` | Vertical right split | `vsplit` |
| `h`, `Ctrl-h` | Horizontal bottom split | `hsplit` |
| `q`, `Ctrl-q` | Close current window | `wclose` |

| `]D` | Go to last diagnostic in document | `goto_last_diag` |

| `]space` | Add newline below | `add_newline_below` |
## Insert Mode
| Key | Description | Command |
| ----- | ----------- | ------- |
| `Escape` | Switch to normal mode | `normal_mode` |
| `Ctrl-x` | Autocomplete | `completion` |
| `Ctrl-w` | Delete previous word | `delete_word_backward` |
## Select / extend mode
I'm still pondering whether to keep this mode or not. It changes movement
commands (including goto) to extend the existing selection instead of replacing it.
> NOTE: It's a bit confusing at the moment because extend hasn't been
> implemented for all movement commands yet.
