# ASCII Keyboard Shortcuts Reference

> All keyboard shortcuts for the ASCII art converter: toggle fullscreen, save PNG, export GIF, play animation preview, and adjust cell size on the fly.

The ASCII art converter responds to keyboard shortcuts so you can perform common actions without reaching for the mouse. Every shortcut listed here maps directly to a button or control already visible in the sidebar — the keyboard just gets you there faster.

<Note>
  Shortcuts are automatically disabled when your cursor is inside a form field — including the custom charset input, the preset name field, any number input, and any dropdown. This prevents accidental triggers while you are typing.

## Shortcuts

| Key            | Action                                   | Notes                                                                                                                                                                               |

| `G`            | Export GIF                               | Same as clicking **Export GIF**; starts the full GIF render pipeline immediately                                                                                                    |
| `Space` or `P` | Play / stop animation preview            | Toggles the parameter-sweep animation preview on and off                                                                                                                            |
| `[`            | Decrease cell size by 1                  | Minimum cell size is 1                                                                                                                                                              |
| `]`            | Increase cell size by 1                  | No upper limit during a live session                                                                                                                                                |

<Tip>
  Press `[` and `]` rapidly to animate cell size changes in real time — you can watch the ASCII resolution shift without opening the animation panel at all.
