# Property editing
In TRIK Studio, there are two ways to edit property values of blocks and links between them:
1. [Using Property Editor panel](#panel).
2. [Directly on the diagram](#diagram).

**Attention!** Editing the properties of the block [Subprogram](https://help.trikset.com/en/studio/blocks#subprogram) is carried out only using the context menu.
{% endhint %}
## Using Property Editor panel
When a block, link, or element is selected, all the properties of the current element are displayed on the [Property Editor](https://help.trikset.com/en/interface#panel-property-editor) panel.
The property editor is a table. In the left column, the property name of the element is displayed, in the right - its value.
You can change the value of any property by clicking on the corresponding cell in the right column and entering the desired value.
For properties that allow only a specific set of values, for example, the “Port” property of the "[Wait for IR distance sensor](https://help.trikset.com/en/trik/programming-visual/blocks#wait-for-infrared-distance)" block, when you try to edit them, a drop-down menu will appear where the desired value is selected:
## Property editing on the diagram
To edit properties directly on the diagram:
1. Hover over the value of the desired property.
2. Double-click the left mouse button to activate editing properties.
3. Enter the desired value.
4. Click on any place in the scene.

**Attention!** This approach can serve as a source of errors, because it allows you to enter an arbitrary text value of the property, including the incorrect one. Be careful.
