# Common interface elements

Because we know that common conventions make things easier for everybody to remember and manipulate, we use a set of common visual symbols throughout Chamilo. These symbols might stand alone representing an action, or be coupled with another symbol representing the object of the action.

Below are listed some of the most commonly used symbols on the platform:

|                               Icons                              | Features                                                                                 |
| :--------------------------------------------------------------: | ---------------------------------------------------------------------------------------- |
|                 ![](/files/-LH9CtvSobLi079kt_43)                 | The pencil tool allows the **updating** of a specific piece of information or content    |
|                 ![](/files/-MFUo6aN02NkZUotP04N)                 | The cross tool allows for the **deletion** of a specific piece of information or content |

|                 ![](/files/-LH9Ctw9L7Mn3xdehtDy)                 | A blue left arrow generally means **go back** (like the back button in your browser).    |
|                 ![](/files/-LH9CtwHDoJOUD5XMaeH)                 | A blue arrow pointing down generally means **download** some file or data.               |
