# Keyboard shortcuts

Quick reference for keyboard shortcuts in the Impossible builder.

## Undo and redo

| Action           | Windows / Linux    | macOS             |
| ---------------- | ------------------ | ----------------- |
| Undo last change | `Ctrl + Z`         | `Cmd + Z`         |
| Redo             | `Ctrl + Shift + Z` | `Cmd + Shift + Z` |

Undo and redo affect the staged state. They do not affect published content.

## Chat

| Action                         | Shortcut               |
| ------------------------------ | ---------------------- |
| Send message                   | `Enter`                |
| New line (in multi-line input) | `Shift + Enter`        |
| Paste image                    | `Ctrl + V` / `Cmd + V` |

## Stop agent

| Action                  | Shortcut                                                              |
| ----------------------- | --------------------------------------------------------------------- |
| Stop streaming response | Click the **Stop** button (square icon) while the agent is responding |

The Stop button appears in place of the Send button when the agent is busy.

## Browser shortcuts

Standard browser shortcuts also work:

* `Ctrl + F` / `Cmd + F` — Find in page
* `Ctrl + R` / `Cmd + R` — Refresh
* `Ctrl + W` / `Cmd + W` — Close tab (you may see a confirmation if you have unpublished changes)

<Note>
  If you have unsaved (unpublished) changes or an active agent turn, closing the tab may show a confirmation dialog to prevent accidental loss.
