# Inserire caratteri speciali

È possibile digitare e visualizzare migliaia di caratteri dalla maggior parte dei sistemi di scrittura del mondo, anche quelli non direttamente presenti sulla tastiera. In questa pagina vengono presentati diversi modi di inserimento di questi caratteri.

## Metodi per inserire caratteri

- Character map
- Compose key
- Code points
- Keyboard layouts
- Input methods

## Character map

GNOME comes with a character map application that allows you to browse all the characters in Unicode. Use the character map to find the character you want, and then copy and paste it to wherever you need it.

You can find Character Map in the dash. For more information on the character map, see the Character Map Manual.

## Compose key

A compose key is a special key that allows you to press multiple keys in a row to get a special character. For example, to type the accented letter é, you can press `compose` then `'` then `e`.

Keyboards don't have specific compose keys. Instead, you can define one of the existing keys on your keyboard as a compose key.

### Define a compose key

1. Fare clic sull'icona a destra nella barra dei menù e selezionare Impostazioni di sistema.

2. Click Region and Language.

3. Select the Layouts tab and click Options.

4. Find the group called Compose key position. Select the key or keys you would like to behave as a compose key. You can choose keys like `Caps Lock`, either of the `Alt` keys, or the menu key. Any keys you select will then only work as a compose key, and will no longer work for their original purpose.

You can type many common characters using the compose key, for example:

- Press `compose` then `'` then a letter to place an acute accent over that letter, such as é.

- Press `compose` then ``` (back tick) then a letter to place a grave accent over that letter, such as è.

- Press `compose` then `"` then a letter to place an umlaut over that letter, such as ë.

- Press `compose` then `-` then a letter to place a macron over that letter, such as ē.

For more compose key sequences, see the compose key page on Wikipedia.

## Code points

You can enter any Unicode character using only your keyboard with the numeric code point of the character. Every character is identified by a four-character code point. To find the code point for a character, find the character in the character map application and look in the status bar or the Character Details tab. The code point is the four characters after U+.

To enter a character by its code point, hold down `Ctrl` and `Shift`, type `u` followed by the four-character code point, then release `Ctrl` and `Shift`. If you often use characters that you can't easily access with other methods, you might find it useful to memorize the code point for those characters so you can enter them quickly.

## Keyboard layouts

You can make your keyboard behave like the keyboard for another language, regardless of the letters printed on the keys. You can even easily switch between different keyboard layouts using an icon in the menu bar. To learn how, see Usare disposizioni di tastiera alternative.

## Input methods

An Input Method expands the previous methods by allowing to enter characters not only with keyboard but any input devices also. For instance you could enter characters with a mouse using a gesture method, or enter Japanese characters using a Latin keyboard.

To choose an input method, right-click over a text widget, and in the menu Input Method, choose an input method you want to use. There is no default input method provided, so refer to the input methods documentation to see how to use them.
