# UI Button Setup

{% hint style="info" %}
**This only needs to be done if you’re setting the canvas buttons yourself or if anything might be missing.**
{% endhint %}

* Select and open out your **one of the canvas UI elements which is a parent of the "UIManager",** to find all the elements.
* Select any of the Button numbers, add an **“OnClick()”** event in the bottom right of the inspector by clicking the **“+”.** (Unless it already has one added).
* Add your **“UIManager”** object to the available slot.
* On the drop down on the right, (No function dropdown if nothing is selected) choose the **“PhoneUIManager”** option which will open out into more.
* Choose **“PhoneUIManager.KeyPressString”**
* You can then add whatever number or keyboard symbol you like in the slot below the dropdown.
* Continue this for each button available. 

{% hint style="warning" %}
**You can select multiple buttons at once!**
{% endhint %}

{% hint style="info" %}

This is very similar setup for the CLOSE / CLEAR / ENTER Button.
{% endhint %}

* Select any of the CLOSE / CLEAR / CALL buttons, add an **“OnClick()”** event in the bottom right of the inspector by clicking the **“+”.**
* Add your **“UIManager”** to the available slot
* On the drop down on the right, choose the **“PhoneUIManager”** option which will open out into more.
* Choose **“PhoneUIManager.KeyPressClose”** or **“PhoneUIManager.KeyPressClr”** or **“PhoneUIManager.KeyPressClass”** to the corresponding buttons.
