### Remarks

Use [Event.character](/engine/6000.5/script-reference/unityengine/event/character.md) to find out what has been typed. Use [Event.keyCode](/engine/6000.5/script-reference/unityengine/event/keycode.md) to handle arrow, home/end or other function keys, or to find out which physical key has been pressed. This event is sent repeatedly depending on the end user's keyboard repeat settings.

Note that key presses can come as separate events, one with valid [Event.keyCode](/engine/6000.5/script-reference/unityengine/event/keycode.md), and another with valid [Event.character](/engine/6000.5/script-reference/unityengine/event/character.md). In case of keyboard layouts with dead keys, multiple [Event.keyCode](/engine/6000.5/script-reference/unityengine/event/keycode.md) events can generate a single [Event.character](/engine/6000.5/script-reference/unityengine/event/character.md) event.
