# Entering ISO-Latin-1 Characters in Amaya

To enter a non-breaking space with Amaya, hold down the `Control` key while pressing the `Space` key. If the document is saved in ASCII, this character is saved as an entity (`&nbsp;`).

To enter ISO-Latin-1 characters that are not directly available from the keyboard, Amaya provides two multi-key input methods:

- Standard multi-key
- Optional multi-key

You choose the method you want to use by selecting Enable multi-key in the General Preferences dialog box, available from the Special menu. When enabled, Amaya activates the optional multi-key support, and deactivates the standard multi-key support.
