# Key Pressed

This Event doesn’t exist by default. Still, you can define to capture the pressing of a specific key or any key (Key Pressed). If you choose to capture a specific key, the Event will be triggered when you press the defined key or by Action:\
\
\- [Send Keys](/kalipso/documentation/actions/group-others/send-keys.md)\
\
If you choose to capture any key, the Event will be triggered when you press any key or by Action:\
\
\- [Send Keys](/kalipso/documentation/actions/group-others/send-keys.md)

{% hint style="info" %}
Pressing a key has 2 moments: pressing down the key and releasing the key. This Event is triggered on when pressing the specified key.
{% endhint %}

{% hint style="info" %}
Although Action ‘[Send Keys](/kalipso/documentation/actions/group-others/send-keys.md)’ can emulate a keyboard Event, if your intention is to simply execute the Actions of that Event, you should use Action ‘[Execute Event](/kalipso/documentation/actions/group-controls/execute-event.md)’. Notice that the ‘Send Keys’ Action sends a message to the windows queue and you don’t control the target of the message. When using the ‘[Execute Event](/kalipso/documentation/actions/group-controls/execute-event.md)’ no message is queued, Kalipso executes directly the Actions defined on the Event, without triggering the Event.
{% endhint %}

{% hint style="info" %}

* If you choose to capture any key, you can use Keyword [KEYPRESSED](/kalipso/documentation/expressions/functions/keywords/keypressed.md) to know its code.
  {% endhint %}
